Suppose that we want to estimate the mean daily profit of a convenience store. For this purpose, we record the daily profit for a random sample of days. The sample

has a mean of 503 dollars and a standard deviation of 73 dollars. For each of the following sampling scenarios, determine which test statistic is appropriate to use when making inference statements about the population mean. |(In the table, Z refers to a variable having a standard normal distribution, and f refers to a variable having at distribution.)
