Chapter 2, Problem 39P
In Section 2.10, we described Data Set BONEDEN.DAT (at www.cengagebrain.com) concerning the effect of tobacco use on BMD.
Suppose we group the twin pairs according to the difference in tobacco use expressed in 10 pack-year groups (0–9.9 pack-years/10–19.9 pack-years/20–29.9 pack-years/30–39.9 pack-years/40+ pack-years). Compute appropriate

According to the National Health and Nutrition Examination Survey (NHANES) sponsored by the U.S. government, a random sample of 712 males between 20 and 29 years of age and a random sample of 1,001 males over the age of 75 were chosen and the weight of each of the males were recorded (in kg). Do the data provide evidence that the younger male population weighs more (on average) than the older male population? Use “Y” for ages 20-29 and “S” for ages 75+. It was found that x̅Y=83.4, sY=18.7, x̅S=78.5, and sS=19.0.

Group of answer choices
0.001 < p-value < 0.002
0.005 < p-value < 0.01

a) Is the normality condition met for this test? (see picture)
No, since the histograms show skewness and outliers .
Yes, since both sample sizes are larger than 30.
No, since both sample sizes, nY and nS, are less than 30.
Yes, since it was stated that the two populations are normally distributed.
