a Since the sampling distribution is approximately normal, use the NORM.DIST function to determine the probability that a randomly selected sample of size n = 60 will have a sample proportion of females less than .2, i.e., 20%.

b. Suppose the company claims that they randomly selected from this population and the random sample contains 8 females out of 60. Draw a data distribution.

c. considering the last part, do you believe that the company truly randomly sampled from the population of all employees?

Sampling with replacement A researcher is interested in drawing a sample of potential voters from a population of 10 individuals. She settles on a sample size of 5, and sends out random invitations to 5 of the voters, by picking their names randomly from a list. How many possible samples could she draw from this population? Sampling without replacement The researcher realizes that she made a mistake! She accidentally asked the selected some of the same voters more than once....

The distribution of the commute times for the employees at a large company has mean 22.4 minutes and standard deviation 6.8 minutes. A random sample of n employees will be selected and their commute times will be recorded. What is true about the sampling distribution of the sample mean as n increases from 2 to 10 ? The mean increases, and the variance increases. A The mean increases, and the variance decreases. B The mean does not change, and the...
