The sample mean of data is 24.19 and median is 3.54. The sign test and hypothesis testing. The boxplot for observation is present above figure. Yes, it support assumption that we are sampling from a normal distribution.

We have a sample data with values 1.48, 4.10, 2.02, 56.59, 2.98, 1.51, 76.49, 50.25, 43.52, 2.96. Also, here consider a sample from a normal distribution with unknown mean and variance, and the hypothesis that the population median (which is the same as the mean in this case) is 3.

Hypothesis testing parameters are

\(Н_0 : \mu = 3 \)

\(H_a : \mu ≠ 3 \)

The sample mean is called the average and it is defined as the ratio sum of data values divided by number of data values.

Median is a statistical measure. It is equals to the middle data value obtained by ordering the data values in ascending order. In case of odd number of data values it is middle value and in case of even number of data values it become mean of two middle values. Here we use Excel function to determine the mean and median values. So, see the above figure, excel command for mean is

'= mean (column contain data values)' and for median '= median ( same column)'. So, mean = 24. 19 and median

= 3.54 . The sign test for hypothesis testing of observations also present in above figure. P-value of test = 0.623 > 0.05 , That is no evidence to reject the null hypothesis. So, population mean = 3. The boxplot of observations also present in above figure.

Answer:

(x + 8)(x + 3)

Step-by-step explanation:

Given

x² + 11x + 24

Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (+ 11)

The factors are + 8 and + 3 , since

8 × 3 = + 24 and 8 + 3 = + 11 , then

x² + 11x + 24 = (x + 8)(x + 3) ← in factored form

Answer:

6 in

Step-by-step explanation:

The angle bisector divides the opposite side into segments that are proportional to the other 2 sides.

let the third side of the triangle be x , then

\(\frac{9}{x}\) = \(\frac{6}{4}\) ( cross- multiply )

6x = 36 ( divide both sides by 6 )

x = 6

The third side of the triangle is 6 in

The perimeter of the rectangle is  4y + 6 (cm).

All four side lengths must be added up in order to get the perimeter, or the distance around the rectangle. Since there are two of each side length, it is simple to multiply the total of the length and the breadth by two in order to do this task effectively. The formula for perimeter is perimeter=(length Plus width)2.

The diagram shows a rectangle. All measurements are in centimetres  an expression in terms of y, for the perimeter of the rectangle.

The perimeter of the rectangle is

2(y+3)+24

=2y + 6 + 2y = 4y + 6 (cm)

False , the variance and standard deviation are not measures of central location

Given data ,

The variance and standard deviation are not measures of central location but measures of dispersion or spread of a dataset

Measures of central location include the mean, median, and mode, which represent the typical or central value of a dataset

The variance and standard deviation are measures of dispersion or spread in a dataset. They provide information about how the values in a dataset are spread out around the mean.

In order to understand the variability or dispersion of data points within a dataset, one must take into account both the variance and standard deviation. They provide information on the range of values and aid in calculating how far away from the mean certain data points are. In statistics and data analysis, these metrics are frequently used to comprehend and evaluate the variance of various datasets.

A 2x3x2 factorial design has three independent variables. What is a factorial design? A factorial design is an experimental design that studies the impact of two or more independent variables on a dependent variable.

The notation of a factorial design specifies how many independent variables are used and how many levels each independent variable has. In a 2x3x2 factorial design, there are three independent variables, with the first variable having two levels, the second variable having three levels, and the third variable having two levels.

The number of treatments or conditions required to create all feasible combinations of the independent variables is equal to the total number of cells in the design matrix, which can be computed as the product of the levels for each factor.

In this case, the number of cells would be 2x3x2=12.Therefore, a 2x3x2 factorial design has three independent variables and 12 treatment groups..

Answer:    y = -1/2x - 2

Step-by-step explanation:

To first write the equation, we need to find the slope and the y intercept and write it in the form  y=mx +b

To find the slope, we will find the difference between the y coordinates and divide it by the difference between the x coordinates.

The y coordinates of the points are , 0 and -2

The x coordinates of the points are -4 and 0

0 - (-2) = 2

-4 -0 = -4

Slope:  2/-4 = -1/2

Now using the formula y=mx+b, you will input the slope and use one of the given point's coordinates to solve for b the y intercept.

We will use the point (0,-2)

  -2 = -1/2(0) + b

-2 = b

  This means the equation will be  y = -1/2x - 2

Answer:

The answer to your problem is, A. The Allstars, with a mean of about 67.1 inches

Step-by-step explanation:

Allstars mean height:

= (73 + 62 + 60 + 63 + 72 + 65 + 69 + 68 + 71 + 66 + 70 + 67 + 60 + 70 + 71) / 15

= 1007 / 15

= 67.6 inches

Super Stars mean height:

= (66 + 68 + 62 + 63 + 47 + 64 + 65 + 50 + 60 + 64 + 65 + 65 + 58 + 60 + 55) / 15

= 912 / 15

= 60.2 inches

We can see that the Allstars team has a higher mean height than the Super Stars team, with an average of 67.6 inches compared to 60.2 inches. Therefore, the Allstars team typically has the tallest players

Thus the answer to your problem is, A. The Allstars, with a mean of about 67.1 inches

a)  The principal is $198,000.

b)   The monthly payment is $1,314.02.

c) The monthly interest rate is 0.0058333 or 0.58333%.

a. To find the principal, we need to subtract the down payment from the purchase price.

Down payment = 10% of $220,000 = 0.10 × $220,000 = $22,000

Principal = Purchase price - Down payment = $220,000 - $22,000 = $198,000

Therefore, the principal is $198,000.

b. To calculate the monthly payment, we can use the formula for a fixed-rate mortgage:

M = P * (r * (1+r)^n) / ((1+r)^n - 1)

Where M is the monthly payment, P is the principal, r is the monthly interest rate, and n is the total number of payments.

For a 30-year mortgage, the total number of payments is 30 years * 12 months/year = 360 months.

First, let's calculate the monthly interest rate. The annual interest rate is 7%, so the monthly interest rate can be found by dividing it by 12.

Monthly interest rate = 7% / 12 = 0.07 / 12 = 0.0058333 (rounded to the hundred-thousandth)

Now we can substitute the values into the formula:

M = $198,000 * (0.0058333 * (1+0.0058333)^360) / ((1+0.0058333)^360 - 1)

Using a financial calculator or software, the monthly payment is approximately $1,314.02.

Therefore, the monthly payment is $1,314.02.

c. The monthly interest rate is already calculated in part b. It is approximately 0.0058333 or 0.58333% (rounded to the hundred-thousandth).

Therefore, the monthly interest rate is 0.0058333 or 0.58333%.

Answer:

Step-by-step explanation:

x^2 + x^2 = 128                 Normally you don't do this but rewrite the question

1x^2 + 1x^2 = 128

You actually do use 1 + 1 = 2 First time I've ever done that.

2x^2 = 128                         Divide by 2

2x^2/2 = 128 / 2

x^2 = 64                            Take the square root of both sides

sqrt(x^2)= sqrt(64)

x = 8
