Which of the following is the name for the statistical hypothesis that describes no change, or nothing expected? Type I error Type II error Alternative hypothesis Null hypothesis
a. If a null hypothesis is rejected with a significance level of 0.05, is it also rejected with a significance level of 0.01? Why or why not? Suppose the level of significance for carrying out the test is lowered from 5% to 1%. As a result, has the likelihood of rejecting the null hypothesis when it is true increased or decreased? Explain
