Question

When H0: μ ≥ 65 vs. Ha: μ < 65, when  is not known, alpha = 0.05, and n =35, the critical value is -1.691.

TRUE or FALSE

Answer 1

if we use z test then critical value will be 1.645 . Therefore given critical value is not appropriate hence answer is false .

suppose we used t text then also the critical value will be 1.6901. therefore given critical value is not appropriate . Hence answer is false.

Answer : FALSE.
