Question 1
A test of hypothesis has the following details:
H0:μ= 8000,Ha: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?
◦
RejectH0 becausep-value <α.
◦
Do not rejectH0 becausep-value <α.
◦
RejectH0becausep-value >α.
◦
Do not rejectH0becausep-value >α.
