Homework Statement
Given that a 95% confidence interval (or 0.05 significance level, α=0.05) for population proportion p is (0.11, 0.17), which statement is true regarding the hypotheses:
(null hypothesis) H0: p = 0.15
(alternate hypothesis) H1: p ≠ 0.15
a) Reject H0 at α = 0.05
b) Reject H0 at α = 0.10
c) Accept H0 at α = 0.05
d) Accept H0 at α = 0.10
Homework Equations
The Attempt at a Solution
Since it's a two-sided test, each side will have α = 0.025 at the 95% significance level. But p = 0.15 is within both α = 0.05 and α = 0.10 isn't it? So wouldn't H0 be accepted at both 0.05 and 0.10?
Kind of lost here. =/
