3. Input POPULATION mean |
once, enter population mean, then ENTER |

In this case, the test was Ha: μ ≠ 64; the one–sample
t statistic is –0.486; the p–value is 0.652; the sample mean is 63.5 and the sample standard
deviation is 2.3. |
9. Draw the test |
repeat steps 1 through 8 (the data should already be stored!), then
once, then ENTER |
