Using the Analysis ToolPak to Perform One-Sample Hypothesis Testing
Using the Analysis ToolPak, complete the following:
Given the following hypotheses:
H0: μ≥ 20
H1: μ < 20
A random sample of five resulted in the following values: 18, 15, 12, 19, and 21. Assume a normal population. Using the .01 significance level, can we conclude the population mean is less than 20? Use the Analysis ToolPak to analyze the data and then use the output from that analysis to make your decision. Describe how you arrived at your decision.
