We have,

When sampling registered voters to gather descriptive statistics for predicting election results, it is important to employ a sampling method that ensures representative and unbiased data.

Here are some approaches to consider:

Random Sampling:

Use a random sampling technique, such as simple random sampling or stratified random sampling. Randomly select registered voters from the voter registration list, ensuring that each voter has an equal chance of being selected.

Stratified Sampling:

Divide the registered voters into relevant demographic groups (e.g., gender, political party, socioeconomic status). Within each group, use random sampling to select an appropriate number of voters proportional to their representation in the population. This helps ensure that each demographic group is adequately represented in the sample.

Cluster Sampling:

Divide the population into clusters, such as geographic regions or voting precincts. Randomly select a few clusters, and then randomly sample registered voters within those selected clusters. This approach can be useful when it is logistically challenging to access the entire population.

Oversampling:

If certain demographic groups are of particular interest due to their potential impact on the election, you may choose to oversample those groups. This involves intentionally selecting more individuals from those groups to ensure sufficient representation in the sample.

Thus,

To sample registered voters for gathering descriptive statistics, use random sampling techniques such as simple random sampling or stratified sampling to ensure representative and unbiased data.

The derivative of f(x) = 4 ln(8 + 9x) is f'(x) = 36/(8 + 9x).

To find the derivative of f(x), we use the chain rule and the derivative of ln(u) = 1/u. Let u = 8 + 9x, then f(x) = 4 ln(u). Using the chain rule, we have:

f'(x) = (d/dx)(4 ln(u)) = 4 (d/dx)ln(u) = 4(1/u) (du/dx)

To find du/dx, we take the derivative of u with respect to x, which is simply 9. Therefore:

f'(x) = 4(1/u) (du/dx) = 4(1/(8 + 9x)) (9) = 36/(8 + 9x)

Therefore, the derivative of f(x) is f'(x) = 36/(8 + 9x).

(a) The accessory shop needs to sell 9 wheels to break even.

(b) The accessory shop will make a profit of $1320.00 each month.

(a) To determine the number of wheels the accessory shop must sell to break even, we need to calculate the break-even point. The break-even point is reached when the revenue equals the total cost. The total cost is the sum of the fixed costs and the variable costs per unit.

Fixed costs: $1020.00

Variable costs per wheel: $155.00 (purchase cost)

Break-even point = Total fixed costs / (Selling price per wheel - Variable cost per wheel)

Break-even point = $1020.00 / ($240.00 - $155.00)

Break-even point ≈ 8.83

Since we cannot sell a fraction of a wheel, the accessory shop must sell at least 9 wheels to break even.

(b) To calculate the monthly profit, we need to subtract the total cost from the total revenue.

Profit per wheel = Selling price per wheel - Variable cost per wheel

Profit per wheel = $240.00 - $155.00 = $85.00

Total profit = Profit per wheel x Number of wheels sold

Total profit = $85.00 x 16 = $1360.00

However, we need to deduct the fixed costs from the total profit to obtain the net profit.

Net profit = Total profit - Fixed costs

Net profit = $1360.00 - $1020.00 = $340.00

Therefore, the accessory shop will make a profit of $340.00 each month.

Statistical inference is the process of using data from a sample to make inferences or conclusions about a population. It allows us to draw conclusions about a larger group of individuals or objects based on information from a smaller sample. It is a fundamental part of statistical analysis and is used in many fields, including research, business, and government.

Statistical inference includes two main types: estimation and hypothesis testing.

Estimation: This involves using sample data to make estimates about population parameters. For example, using the sample mean to estimate the population mean or the sample proportion to estimate the population proportion.

Hypothesis testing: This involves using sample data to test a claim or hypothesis about a population parameter. For example, testing the claim that a coin is fair, based on the proportion of heads in a sample of coin flips.

The goal of statistical inference is to use the information from a sample to make informed decisions or predictions about a population. It allows us to draw general conclusions from a specific set of data, and it is an essential tool for making sense of data in many fields.

The angles of a triangle with side lengths 5 , 12 and 13 are 90°, 22.63°, 67.38°.

In trigonometry, the law of cosines, also known as the law of cosines or cosine formula, basically relates the length of a triangle to one cosine of its angle. It states that if we know the lengths of two sides of a triangle and the angle between them, we can determine the length of the third side. c² = a²+ b² – 2ab cosγ

where a, b, c are the sides of the triangle and γ is the angle between a and b, see image above.

To find the length of a side of a triangle, take △ABC according to the cosine formula, which can be written as follows.

We have , a = 5 , b = 12 , c= 13

cos α =( 12² + 13² - 5² )/2×12×13= 288/312

=> α = cos⁻¹(0.923 ) = 22.63°

cos β = (5² + 13² - 12² )/2×13×5 = 50/130

=> β = cos⁻¹(5/13) = 67.38°

cos γ = (12² + 5² - 13² )/2×12×5= 0

=> γ = cos⁻¹(0) = 90°

Hence, the required angles are 90°, 22.63°, 67.38°.

Therefore any set of data that satisfies the 5-Number summary: 16,18,22,26 and 28 can be represented with the box plot.

Step-by-step explanation:

Interpreting Box Plots

We use a box plot to present the 5-Number summary of a set of data.

The values contained in the 5-Number summary are:

In the box plot, the following rules apply:

Using these, we interpret the given box plot

A left whisker extends from 16 to 18, therefore:

The box extends from 18 to 26 and is divided into 2 parts by a vertical line segment at 22.

The right whisker extends from 26 to 28.

Therefore any set of data that satisfies the 5-Number summary: 16,18,22,26 and 28 can be represented with the box plot.

Box plot has boxes with some lines ( called whiskers ).

Box plot on the graphical level tells about 5 points:

There is starting whisker or left whisker denoting point minimum (Q0) and extends from there the line to Q1 ( first quartile).

Then the box starts which starts from Q1 and touched Q3. In the middle it passes through Q2 ( The median of the data ), and thus has a line in it.

At last, there is end whisker or right whisker denoting end quantile or Q4 (the maximum point).

Given data:

Left whisker extends from 16 to 18.

     Thus Q0 = 16

              Q1 = 18

Box plot starts from 18 and extends to 26, and is split by a vertical line segment at 22.

    Thus Q2 = 22

             Q3 = 26

The right whisker or end whisker extends from 26 to 28

    Thus Q4 = 28.

Thus the description of data is given as:

\(Q_0 = Minimum = 16\\Q_1 = First\: quartile = 18\\Q_2 = Second \:quartile = Median= 22\\Q_3 = Third\: quartile = 26\\Q_4 = Maximum = 28\\\)

The revised MeanMedian2 class allows the user to input up to 20 values, with the option to stop entering numbers by inputting 9999. It calculates both the mean and median of the provided values.

To implement this functionality, the MeanMedian2 class can prompt the user to enter values in a loop until either 20 values are entered or the user inputs 9999. The entered values can be stored in a list. Once the user is done entering values, the class can compute the mean and median. For the mean, it can sum all the values in the list and divide by the number of values. For the median, it needs to handle two scenarios: an odd number of values and an even number of values. If the list has an odd number of values, the median can be obtained by simply finding the middle value. However, if there is an even number of values, the two middle values can be averaged to get the median.

With this revised class, users can easily input any number of values, up to 20, and get accurate mean and median calculations. Additionally, the option to quit by entering 9999 provides a convenient way for users to stop entering values whenever they want. This updated implementation improves the flexibility and usability of the MeanMedian2 class.

The correct answer is option c A stem plot of the data would be skewed right.

A median that is larger than the mean in a set of exam scores suggests that the data is skewed to the right (or positively skewed), meaning that there are more scores at the high end of the distribution. This results in a longer tail on the right side of the distribution, which is often seen in data that contains outliers or extreme values. In this case, a stem plot of the data would be skewed to the right, showing a long tail on the right side of the plot.

Option a (a stem plot of the data would be symmetric) is incorrect because a symmetric distribution would have a median and mean that are equal, which is not the case here.

Option b (a stem plot of the data would be skewed left) is incorrect because a skewed left distribution would have a median that is smaller than the mean, which is not the case here.

Option d (the data set must be so large that it would be better to draw a histogram rather than a stem plot) is incorrect because the size of the data set does not affect the skewness of the data or the choice of a plot to use.

When a widget of price $704 dropped to $336 over eight years, the linear trend of price can be expressed as y = -46x + 704, where y is the price of the widget and x is the number of years passed.

Therefore, the answer is y = -46x + 704

A linear trend implies the trend can be represented by a linear equation. The highest power of variable in a linear equation is 1.

Let us say the trend is expressed as y = mx + c, where y is the price of the widget and x is the number of years passed.

Initially, that is when x = 0 the price is $704. Substituting this

704 = m × 0 + c

Therefore, c = 704.

Over 8 years, that is when x = 8 the price is $336. Substituting this

336 = m × 8 + 704
