Question

When the following hypotheses are being tested at a level of significance of

aH0: m 100
Ha: m < 100

the null hypothesis will be rejected if the test statistic Z is

a. >Z
b. >Z
c. <Z
d. <100

Answer 1

You are lacking information on variability and level of significance used (e.g., P ≤ .05, P ≤ .01).

It would also help if you proofread your questions before you posted them. Choices a and b are identical.
