Question 2: Estimation and
Hypothesis Tests-Two Populations.
In a survey, two independent random
samples of workers of sizes m = 124 and n = 130
from two construction firms, were asked if they wear security
helmets all the time. In the first sample 106 said yes, while in
the second 98 said yes. Let p1 and
p2 be the population proportions of workers of
the two firms who wear their security helmets all the time.
