Question
Consider a dataset containing the heights of 38 females who said they prefer to
sit in the front of the classroom yields a sample average of 62 inches and a
sample standard deviation of 2.5 inches. Suppose that the average height for
the general population of college females is 65 inches. An analyst wants to test
the claim that the true average height of females who prefer to sit in the front
of the classroom is lower than it is for the general population.
In the hypothesis for the above claim (at significance level of 10%), the
appropriate test, test statistic (name and value), and pvalue is
the approximate Z-test with z-statistic = 62 and pvalue = 0.
the approximate Z-test with z-statistic = 7.40 and pvalue
not calculable because normality is not given.
=
0.
the approximate Z-test with z-statistic = -7.40 and pvalue = 0.
