Child Health and Development Studies (CHDS) has been collecting data about 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 37 expectant mothers have mean weight increase of 16.2 pounds in the second trimester, with a standard deviation of 5.6 pounds.
A hypothesis test is done to see if there is evidence that weight increase in the second trimester is greater than 14 pounds.
Find the p-value for the hypothesis test.
The p-value should be rounded to 4 decimal places.

Birth weight and gestational
age. The Child Health and Development Studies
considered pregnancies among women in the San Francisco East Bay
area. Researchers took a random sample of 50 pregnancies and used
statistical software to construct a linear regression model to
predict a baby's birth weight in ounces using the gestation age
(the number of days the mother was pregnant). A portion of the
computer output and the scatter plot is shown below. Round all
calculated results to four decimal places....

Bill, a licensed practical nurse (LPN) is collecting admission
data on Mr. Howell, who has been admitted for dyspnea and weight
loss. While questioning Mr. Howell, Bill learns that he has had
progressive weight loss during the past several months and that he
has had a productive cough. He also reports waking up at night
