Question

Please help solve and explain how the answers where derived. I want to understand the procedure. Thank you!

In a large set of measurements on nonpregnant women, the average fasting
blood glucose level was about 80 milligrams/100 milliliters of blood. Research-
ers determined fasting blood sugar levels for 52 women during their third
trimester of pregnancy (contributed by C. M. Mahan to a collection of prob-
lems in Andrews and Herzberg, 1985, pages 211-214; from O'Sullivan and
Mahan, 1966). The results (in mg/100 ml) are shown here (sample size = 52,
mean = 70.12, sample standard deviation = 9.68).

a. Plot these measurements.
b. How do these blood sugar levels for pregnant women compare with the
average level of 80 mg/100 ml for nonpregnant women? State and test ap-
propriate hypotheses.
c. Calculate an interval estimate for the mean fasting blood sugar level of
women in their third trimester of pregnancy.
