Expectant mothers in oakland, ca since 1959. one of the measurements taken by chds is the weight increase (in pounds) for expectant mothers in the second trimester. in a fictitious study, suppose that chds finds the average weight increase in the second trimester is 14 pounds. suppose also that, in 2015, a random sample of 40 expectant mothers have mean weight increase of 16 pounds in the second trimester, with a standard deviation of 6 pounds. at the 5% significance level, we can conduct a one-sided t-test to see if the mean weight increase in 2015 is greater than 14 pounds. statistical software tells us that the p-value = 0.021. which of the following is the most appropriate conclusion? group of answer choices there is a 2.1% chance that mean second trimester weight gain for all expectant mothers is 14 pounds in 2015. there is a 2.1% chance that mean second trimester weight gain for all expectant mothers is 16 pounds in 2015. there is 2.1% chance that the population of expectant mothers will have a mean weight increase of 16 pounds or greater in 2015 if the mean second trimester weight gain for all expectant mothers was 14 pounds in 1959. there is a 2.1% chance that a random sample of 40 expectant mothers will have a mean weight increase of 16 pounds or greater if the mean second trimester weight gain for all expectant mothers is 14 pounds.
