A) Each dot on the dotplot represents the mean of a single sample of size n = 50.

B) An approximate value for the population mean cannot be determined from the given information.
In the context of the dotplot you described:
a. Each dot in the dotplot represents the mean of a sample of size n=50 drawn from the population. The dotplot shows the distribution of these sample means. b. To approximate the population mean, you can find the central tendency of the dotplot. This can be done by looking for the center point or calculating the average of the sample means displayed. If the dotplot is roughly symmetrical, the center point should give a good approximation of the population mean.

The median price from the given data is 648,303.

To find the median price from the given data, we need to arrange the prices in ascending order and then locate the middle value. If there is an odd number of data points, the median will be the middle value. If there is an even number of data points, the median will be the average of the two middle values.

Let's arrange the data in ascending order:

181,386,243,922,355,008,406,791,542,820,648,303,782,200,845,053,924,494,1,089,774,1,175,704,1,274,928,1,308,954

There are a total of 13 data points, which is an odd number. So, the median price is the middle value.

The middle value is the 7th value:

Median Price = 648,303

Therefore, the median price from the given data is 648,303.

When we use a sample to make statements about or to draw conclusions about a population, we are using statistical inference.

Statistical inference is the process of drawing conclusions about a population by analyzing data from a sample drawn from that population.A statistical inference involves estimating characteristics of a population based on information from a subset of that population, which is the sample. It aims to infer knowledge about a larger group or a population, such as average income or the proportion of people who vote for a certain candidate, by examining data from a smaller portion of the population (a sample).

The sample is used to draw conclusions about the population from which it was selected. Statistical inference techniques are used to determine how accurate these conclusions are likely to be. These techniques include estimation, hypothesis testing, and confidence intervals.

Answer:

Your friend is correct and its 15

Step-by-step explanation:

15 = 3*5

30 = 2*3*5

GCF = 3*5 = 15

The error bound for the 95% confidence interval ≈ 0.800.

To construct a confidence interval for the true population mean, we can use the formula:

Confidence Interval = Sample Mean ± Margin of Error

The margin of error depends on the desired confidence level, the sample standard deviation, and the sample size.

In this case, the desired confidence level is 95%.

The margin of error can be calculated using the formula:

Margin of Error = Critical Value * (Sample Standard Deviation / √Sample Size)

Since the population is assumed to be normally distributed, we can use the Z-distribution and find the critical value associated with a 95% confidence level.

The critical value for a 95% confidence level corresponds to a Z-score of approximately 1.96.

We have:

Sample Mean (xbar) = 13.10

Sample Standard Deviation (s) = 1.55

Sample Size (n) = 15

Critical Value (Z) = 1.96

Calculating the margin of error:

Margin of Error = 1.96 * (1.55 / √15) ≈ 0.800

Therefore, error bound ≈ 0.800.

The solution to the system of equations is x = 1 and y = -1. Substituting these values into the equations satisfies both equations simultaneously. Therefore, (1, -1) is the solution to the given system of equations.

To solve the system, we can use the method of substitution or elimination. Let's use the substitution method. From the first equation, we can express y in terms of x as y = 3x - 4. Substituting this expression for y into the second equation, we have \(6x^2 - 11x - (3x - 4) = -4\). Simplifying this equation, we get \(6x^2 - 14x + 4 = 0\).

We can solve this quadratic equation by factoring or using the quadratic formula. Factoring the equation, we have (2x - 1)(3x - 4) = 0. Setting each factor equal to zero, we find two possible solutions: x = 1/2 and x = 4/3.

Substituting these values of x back into the first equation, we can find the corresponding values of y. For x = 1/2, we get y = -1. For x = 4/3, we get y = -11/3.

Therefore, the system of equations is solved when x = 1 and y = -1.

The difference in the dollar value of Assistantship (Stipend) between art and science fields with  standard errors is equal to 1.214.

Mean      24041.62203                 25952.36501

Sample mean difference between Assistantship (stipend) in arts and science is equal to

=  $25952.36501 - $24041.62203

= $1910.74298.

Hypothesized mean difference is 0 (there is no difference in stipend between the two fields).

Variance        621483.0801            615193.5853

Sample size    521                             479

Standard error of the difference is,

=√[(variance in arts / sample size in arts) + (variance in science / sample size in science)]

= √[(615193.5853 / 479) + (621483.0801 / 521)]

= $49.77

t-statistic

= (sample mean difference - hypothesized mean difference) / standard error of the difference

Substitute the values into the t-statistic formula,

⇒ t-statistic = ($1910.74298 - 0) / $49.77

⇒ t-statistic = 38.39

t-critical value for a two-tailed test with 992 degrees of freedom at a significance level of 0.05 is 1.9624.

t-statistic (38.39) > t-critical value (1.9624)

⇒Reject the null hypothesis that there is no difference in stipend between the two fields.

standard errors

= t-statistic / √(sample size)

= 38.39 / √(479 + 521)

= 38.39 /31.62

=1.214

Therefore,  the difference in the dollar value of Assistantship (Stipend) between these two fields is 1.214 standard errors away from the hypothesized difference.
