Wé wish tó éstimaté the mean price of gasoline (per gallon) at gas stations across Saskatchewan, assuming that these prices are normally distributed with a population standard deviation of 16.1 cents. We want to determine the minimum sample size that is required, if we want our 99% interval estimate to have a maximum error of 4 cents. Note: For the calculation below, choose the appropriate z-score value from the following list: 1.05, 1.28, 1.44, 1.645, 1.88, 1.96, 2.1, 2.33, 2.575 The minimum sample size is = What are we actually sampling? In other words, what does the sample size refer to?
