2.5.3 Hypothesis test for a Normal mean (A-level only)

Which parameter must hypotheses about a population mean use?

A

There is insufficient evidence to suggest the claim in H1H_1H1​; do not accept H0H_0H0​.

B

If H0H_0H0​ is true, the standardised statistic has distribution Z∼N(0,1)\boxed{Z\sim N(0,1)}Z∼N(0,1)​.

C

The upper-tail critical value for a 5% test is approximately 1.645\boxed{1.645}1.645​.

D

Use the population mean μ\muμ, not the sample mean xˉ\bar xxˉ.
