Question

Transcribed Image Text: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 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 x = 67.1, n = 36, and assume that o = - 18.3.
