The average amount of rainfall during the summer months for the midwestern part of the US is more than 13 inches. Rainfall amounts are generally normally distributed. A researcher selects a random sample of 15 cities in the Midwest and finds that the average amount of summer rainfall is 11.42 inches. The standard deviation of the sample is 2.13 inches. Using α = 0.05, can it be concluded that the mean rainfall in the Midwest is more than 13 inches? What is the decision for this hypothesis test? The average amount of rainfal

Fail to reject the null because the test statistic is not in the critical region and the p-value is greater than alpha.
Fail to reject the null because the test statistic is not in the critical region and the p-value is less than alpha.
Reject the null because the test statistic is in the critical region and the p-value is less than alpha.
