16. A significance test for a population mean uses a significance level of 5%. If the
hypothesized mean is 12 feet, the alternative hypothesis is that the population
mean is greater than 12 feet, the sample standard deviation is 1.7 feet, and the
sample size is 30, what is the minimum sample mean that will lead to rejecting
the null hypothesis? (Assume the conditions for the test are met.) *
