You are attempting to determine the average grade (out of 100%) of students at MIT. You have taken 100 independent random samples of size 50 from that population and calculated the sample mean (x̄ ) and a sample variance (s^2 ) of each sample.

  1. What distribution would you expect the 100 sample means ( x̄) you have calculated to follow? Why?
  2. What distribution would you expect the 100 sample variances (s^2 ) to follow?

Suppose Jack and Diane are each attempting to use a simulation to describe the sampling distribution from a population that is skewed right with mean 50 and standard deviation 15. JackJack obtains 1000 random samples of size n=55 from the​ population, finds the mean of the​ means, and determines the standard deviation of the means. Diane does the same​ simulation, but obtains 1000 random samples of size n=40 from the population. Complete parts​ (a) through​ (c) below. a) Describe the...

You are interested in estimating the average height in a class of 100 students. In this class the mean height is 65 inches and the standard deviation is 4 inches. You take a sample of size 16 and compute the average (mean) height of the sample which is 64 inches. If we are sampling with replacement, how many different samples (keeping track of order) of size 16 are possible? (Do not compute this, just explain how to compute it.) What...

Suppose the population consists of FIVE individuals and the elements are: S= {3, 6, 9, 12, and 15} Obtain samples of size 3 (use counting rule). Obtain the population mean and variance, sample means and variances of the distribution. Would the mean and variance change if the sample size were to increase? Prepare two excel tables. a) In an excel table show the various samples (Table-1). b) Calculate the population mean and variance (Table-1). c) Calculate the sample mean and...

P2. Suppose you want to compare the weekly study hours of Statistics and Economics students. For this, a random sample of 20 students of Statistics was taken, from which an average of 3 hours per week was obtained with a deviation. typical of 2.5h, and another sample of 30 students of Economics independent of the previous one, who presented an average of 2.8 h, with a deviation. typical 2.7h. Assuming that the weekly study hours of the two types of...

1. What is a characteristic of the repeated-measure design? A. The test requires a larger sample size compared to a between-subjects design. B. More than one measure is taken from each subject. C. There are usually two groups of subjects to be compared. D. The appropriate hypothesis test is typically independent-samples t-test. 2. Which is the best way to reduce the variance in the distribution of means (also called sampling distribution) when conducting a t test? A. Ensuring that the...
