For a hypothesis test of a single population mean with known population standard deviation (o), we can use either Geogebra or Minitab. In Geogebra, use the "Statistics" tab in the Probability Calculator in Geogebra. If needed, click the drop-down menu near the top and sele "Z Test of a Mean" (this is the default). In Minitab, use Stat > Basic Statistics >1 sample Z. Select Summarized Data from the drop-down menu. Check mark "Perform Hypothes Test" and enter the hypothesized value. Click Options and select the appropriate alternative hypothesis. In either program, enter the sample mean, population standard deviation, and sample size. We'll use a sample with x = 67.1, n = 36, a assume that o = 18.3. For a hypothesis test of Ho : u = 60 versus HA : u > 60: • The given sample has a test statistic of 2.3279 • The P-value for the test is 0.01 For a hypothesis test of Ho : µ = 70 versus HA : u < 70: • The given sample has a test statistic of 3.2789 • The P-value for the test is 0.9995 For a hypothesis test of Ho :u = 70 versus HA : u# 70: • The given sample has a test statistic of 3.2789 • The P-value for the test is 0.001
