One of the measurements taken by CHDS is the age of first 10 pointstime expectant mothers. Suppose that CHDS finds the average age for a first time mother is 26 years old. Suppose alsothat, in 2015, a random sample of 50 expectant mothers have mean age of 26.5 years old, with a standard deviation of1.9 years. At the 5% significance level, we conduct a one-sided T-test to see if the mean age in 2015 is significantlygreater than 26 years old. Statistical software tells us that the p-value = 0.034.Which of the following is the most appropriate conclusion?A. There is a 3.4% chance that a random sample of 50 expectant mothers will have a mean age of 26.5 yearsold or greater if the mean age for a first time mother is 26 years old.B.
