Consider the following results for independent samples taken
from two populations.
n1 = 400
n2 = 300
p1 = 0.52
p2 = 0.34
(a)
What is the point estimate of the difference between the two
population proportions? (Use
p1 − p2.
)
(b)
Develop a 90% confidence interval for the difference between the
two population proportions. (Use
p1 − p2.
Round your answer to four decimal places.)
to
(c)
Develop a 95% confidence interval for the difference between the
two population proportions. (Use
p1 − p2.
Round your answer to four decimal places.)
