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.
