Question 1

A test of hypothesis has the following details:

H₀:μ= 8000,H_a:μ> 8000,n= 50,σ= 409,α= 0.01,\(\style{font-family:Times New Roman;}{\overline x}\)= 8158

Calculate thep-value and state the correct decision for this test.

◦

p-value = 0.0032; fail to rejectH₀

◦

p-value = 0.3863; fail to rejectH₀

◦

p-value = 0.3483; rejectH₀

◦

p-value = 0.0032; rejectH₀

Question 2

A two-tailed test of hypothesis has ap-value = 0.0055. The critical value from the test is 0.9800. The type I error probability for the test is 0.01. What is the correct decision for the test and why is this reason correct?

◦

RejectH₀becausep-value <α.

◦

Do not rejectH₀becausep-value <α.

◦

RejectH₀becausep-value >α.

◦

Do not rejectH₀becausep-value >α.
