Based on the z-statistic of –2.5 for the sample data, should the null hypothesis be rejected? Yes, because the z-statistic lies
within the critical region. Yes, because the z-statistic lies outside of the critical region. No, because the z-statistic lies within the critical region. No, because the z-statistic lies outside of the critical region.
No, because z-statistics lies within the critical region.
Step-by-step explanation:
The z value is calculated to determine whether the null hypothesis should be accepted or rejected. The null hypothesis is rejected when the z-value lies outside the critical region. The critical region is determined by the sample data.
