See below. I need help with the p-value that came back wrong in the red box. Everything else is right!!
For a hypothesis test of a single population mean with known population standard deviation (0), 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 select
"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 Hypothesis
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 = 67.1, n = 36, and
assume that o = 18.3.
For a hypothesis test of Ho :µ = 60 versus HA : µ > 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 : µ < 70:
• The given sample has a test statistic of
-0.95
• The P-value for the test is 0.171
For a hypothesis test of Ho :µ = 70 versus HA : u + 70:
-0.95
• The given sample has a test stątistic of
• The P-value for the test is 0.342
