You are about to conduct a study of mortgage loans for people who have graduated college in the past 5 years. From a pilot study, you estimate that the standard deviation of these mortgages is about $66,000. What sample size would you actually need to use in order to have a margin of error no greater than $5,000 with 97.5% confidence? The z-value needed for this is: [a] The sample size is [b] Retype your answer. [c]

The image below illustrates which sampling technique?

In 2020, the final exam scores of students taking an introductory statistics class was normally distributed with a mean score of 149 and a standard deviation of 16. What is the probability that the average final exam score for a sample of 64 students was between 140 and 150? (Enter all values for the indicated steps in your solutions) [a][b] [c] – [d] = [e]
