26 pоints) Ten students were rаndоmly selected frоm а lаrge class and given a test printed on yellow paper. Here are their scores on the test. Suppose the population is normal. a) (3 points) What are the requirements to construct a confidence interval for estimating a population mean? b) (4 points) What is the mean and standard deviation of the sample? Round to one decimal place. c) (4 points) What is the best point estimate for the population mean and what is the value of the best point estimate? d) (4 points) Construct a 95% confidence interval for this situation. Round the interval to one decimal place. e) (3 points) What is the margin of error for your interval? f) (4 points) Write an interpretation for the confidence interval g) (4 points) Suppose that you took 200 more samples of 10 students and constructed confidence intervals with a 90% confidence level. How many of those intervals do you expect to contain the true population mean?
