(See Steps) Based on the information given for each of the following studies, decide whether to reject the null hypothesis. For each, give the Z—score cutoff
Question: Based on the information given for each of the following studies, decide whether to reject the null hypothesis. For each, give the Z—score cutoff (or cut— offs) on the comparison distribution at which the null hypothesis should be rejected, the Z score on the comparison distribution for the sample score, and your conclusion. Assume that all populations are normally distributed.
| Study | \[\mu \] | \[\sigma \] | Sample Score | p | Tails |
| A | 5 | 1 | 7 | 0.05 | 1 |
| B | 5 | 1 | 7 | 0.05 | 2 |
| C | 5 | 1 | 7 | 0.01 | 1 |
| D | 5 | 1 | 7 | 0.01 | 2 |
