Explanation:
Detailed explanation-1: -The answer is “FALSE.” To not reject the null hypothesis at the significance level of 0.10, the p-value has to be above 0.10 . If the p-value is above 0.10, it is also above 0.05; the null hypothesis is not rejected at 0.05 significance either.
Detailed explanation-2: -To graph a significance level of 0.05, we need to shade the 5% of the distribution that is furthest away from the null hypothesis. In the graph above, the two shaded areas are equidistant from the null hypothesis value and each area has a probability of 0.025, for a total of 0.05.
