Question

If the proportion under the curve that corresponds to the obtained z score is smaller than rejection areas, what decision can we make about rejecting the null hypothesis?

1) Reject the null hypothesis
2) Fail to reject the null hypothesis
3) Cannot be determined based on given information

Answer 1

The decision that can be made about rejecting the null hypothesis is to Reject the null hypothesis.

Step-by-step explanation:

The decision that can be made about rejecting the null hypothesis is to Reject the null hypothesis.

In hypothesis testing, if the proportion under the curve that corresponds to the obtained z score is smaller than the rejection areas, it means that the obtained result is statistically significant and provides enough evidence to reject the null hypothesis.

This decision is based on comparing the obtained z score to the critical values or comparing the p-value to the significance level (alpha), and if the obtained result falls into the rejection region, the null hypothesis is rejected.
