We have a left tail one sample test for the population mean. Assume the null hypothesis is true. Use 4% for the significance level. The sample size is 27, the sample mean is 32.8, the sample standard deviation is 4.1, and the null mean is 35.

The test result is (a) a correct decision (b) a Type I error (c) a Type II error 3.

The test statistic value for the previous problem is

Indicate whether the following statement is true or false. If we do not reject the null hypothesis, it is possible we have made both type I and type II errors. In an upper tail hypothesis test for the mean, the critical value is 2.575 and the test statistic is 2.5. In this case, the null hypothesis should not be rejected. The calculated p-value should be divided by 2 to make the decision for a two tail test. The sampling error...
