You would like to construct a 90% confidence interval to estimate the population mean price of milk (per gallon) in your city. You select a random sample of prices from different stores. The sample has a mean of 3.66 dollars and a standard deviation of 0.30 doktors (a) What is the best point estimate, based on the sample, to use for the population mean? Idollars (b) For each of the following sampling scenarios, determine which distribution should be used to calculate the critical value for the 90% confidence interval for the population mean (In the table, 2 refers to a standard normal distribution, and t refers to a e distribution) Could use Sampling scenario 2 1 Unclear either Zort X The sample has size 10s, and it is from a non norhilly distributed population The sample has size 75, and it is from a non-normally distributed population with a known standard deviation of 0.29 o .
