D.
Step 1 :We are given a test statistic of
Step 2 :We need to compare the test statistic with the critical value. The critical value for a right-tailed test with a significance level of 0.01 is the z-score that corresponds to the 99th percentile of the standard normal distribution.
Step 3 :Using a standard normal distribution table, we find that the critical value is approximately
Step 4 :If the test statistic is greater than the critical value, we reject the null hypothesis. If the test statistic is less than or equal to the critical value, we fail to reject the null hypothesis.
Step 5 :Since the test statistic
Step 6 :
