When using null hypothesis statistical testing (NHST) and you decide to change t

Question

When using null hypothesis statistical testing (NHST) and you decide to change the alpha from alpha =.01 to alpha .05: 1. A (larger, smaller) z-score is required to reject the null hypothesis 2. The upper limit of the probability of a type 1 Error (decreases, increases) 3. Cohen’s d will be (unaffected, smaller, larger)

Please explain each answer

Explanation / Answer

1)as we are increasing level of significance that means we are increasing the chance to reject null hypothesis for which we need smaller z score.

2) Increases ; as alpha level itself is a type I error

3) unaffected: as it does nt depend on level of significance.
