For Hypothesis Lower Tail Test Value approach, which of the following is correct ? |
Reject $H_0 $ if $Z≤-Z \alpha $ Reject $H_0 $ if $Z≥ Z \alpha $ Reject $H_0 $ if $Z< Z \alpha $ Reject $H_0 $ if $Z> Z \alpha $ |
Reject $H_0 $ if $Z≤-Z \alpha $ |
The correct answer is Option (1) → Reject $H_0 $ if $Z≤-Z \alpha $ The rejection region is in the left tail. One reject $H_0$ if the test statistic z is less than or equal to $-Z \alpha $ |
