Humans are known to have a mean gestation period of 280 days (from last menstruation) with a standard deviation of about 9 days. A hospital wondered whether there was any evidence that their patients were at risk for giving birth prematurely. In a random sample of 70 women, the average gestation time was 277.7 days. Is the alternative hypothesis one-sided or two-sided? (type your choice as either one-sided or two-sided) What is the value of the test statistic? (round to 3 decimal places) What is the P-value of the test? (round to 3 decimal places) What is the conclusion of the test if alpha is 0.05? (type your choice as either reject or fail to reject)
