Question

p-value Approach: The p-value is the smallest significance level at which the null hypothesis is rejected. While using the normal distribution, suppose, z = Zobserved is the test statistic value for testing the hypothesis about a population mean. This test statistic value is usually negative for a left-tailed test and is usually positive for a right-tailed test. The p-value is obtained with the help of the Standard Normal Distribution Table (Table IV). 1. For a left-tailed test, p-value = P(z< Zobserved) 2. For a right-tailed test, p-value = P(z zobserved 3. For a two-tailed test, p-value = 2P 2 observed red) With the help of the provided information, fill in the blanks in the table below. (Note: Enter just the numerical values, round the p-value to 4 decimal places of accuracy, and in the last column, enter) if you reject Ho enter 2, otherwise.) and
