Ti-84
A research group claims that less than 25% of students at one
medical school plan to go into general practice. It is found that
among a random sample of 120 of the school's students, 20% of them
plan to go into general practice. At the 0.10 significance level,
do the data provide sufficient evidence to conclude that the
percentage of all students at this school who plan to go into
general practice is less than 25%? Use the confidence...

A business students claims that on average an MBA students is
required to prepare more than five cases per week. To examine the
claim, a statistics professor ask a random sample of ten MBA
students to report the number of cases they prepare weekly. The
results are given below. Can the professor conclude that the claim
is true, at the .05 level of significance, assuming the number of
cases is normally distributed with a standard deviation of 1.5?

Are medical students more motivated than law students?
A randomly selected group of each were administered a survey of
attitudes toward Life, which measures motivation for upward
mobility. The scores are summarized below. The researchers suggest
that there are occupational differences in mean testosterone level.
Medical doctors and university professors are two of the
occupational groups for which means and standard deviations are
recorded and listed in the following table.

A researcher claims that more than 30 percent of students of WPU
use reading glasses. A consumer agency wants to test this claim.
The agency takes a random sample of 120 students and finds that 60
of them use reading glasses. If the agency conducts hypothesis
testing, which would be the computed p-value for the test?

A labor union claims that the mean income of its members is no
more than $20,000 per year. The Employers' Association believes
that this claim is too low and that the actual mean income is
higher. A random sample of 64 union members yields a mean income of
$20,278.50 with a standard deviation of $793.81. Calculate the
standardized test statistic and find the P-value.
