Summary:: Confused on correction for contunuity
I'm confused about one step for questions like this where you have to determine to accept or reject the null hypothesis.
Sample size: 50
Number of successes: 23
Significance level: 10%
Null hypothesis: p = 0.4
Accepted hypothesis: p > 0.4
Solution:
μ = np
= (50)(0.4)
= 20
σ = √npq
= √(20)(0.6)
= 3.46
This is the part I'm confused on: To determine if I should accept/reject the hypothesis, would I do 1) or 2) or 3)
1) P ( x̅ >23)
= P ( x̅ > 23.5)
= 1-P(x̅<23.5)
and then solve
2) P ( x̅ >23)
= 1 - ( x̅ < 22.5)
and then solve
3) P ( x̅ < 23)
=P ( x̅ < 22.5)
and then solve
