Question
Solve the following proportion hypothesis:
Give: Ho: p ≤ 0.6
H1: p > 0.6
A binomial distribution can be approximated with thenormal distribution , so use a
z-score for α=0.05.
Test the above hypothesis is a random sample of 250 users has 210 successes.
Solution: [Write rules/formula]
Calculate p̄ :
Calculate Zp :
Find Zα :
Compare Zp and Zα :
Conclusion:
-Suppose we fail to reject Ho: μ ≥ 50 When the true mean is μ = 53
Given a sample of size n=64 and σ =6 and with α=0.05
Calculate the critical sample mean Xα , the ZX̅α , The probability of type II error β
and the power of the hypothesis test P.
Solution: [Write the rules/formula]
Calculate X̅α :
Calculate ZX̅α with the true mean μ = 53:
The probability of type II error β:
The power of the hypothesis test P:
