Question

How tackle.. need help..i have to Complete my work...can i get help.

Bob selects independent random samples from
two populations and obtains the values p1 =
0.700 and p2 = 0.500. He constructs the 95%
confidence interval for p1 – P2 and gets:
0.200 ± 1.96(0.048) = 0.200 ± 0.094.
Note that 0.048 is called the estimated standard
error of p1 – P2 (the ESE of the estimate).
Tom wants to estimate the mean of the success
rates:
Pi +P2
(a) Calculate Tom's point estimate.
(b) Given that the estimated standard er-
ror of (p1 + p2)/2 is 0.024, calculate
the 95% confidence interval estimate of
(P1 + p2)/2. Hint: The answer has our
usual form:
Pt. est. +1.96 x ESE of the estimate.
