A microbiologist wishes to determine whether there is any
difference in the time it takes to make yogurt from two different
starters: lactobacillus acidophilus (A) and bulgarius (B).
Seven batches of yogurt were made with each of the starters. The
table below shows the time, in hours, to make each batch. Assume
that both sets of times may be considered to
be random samples from normal populations. Determine whether the
mean time taken to make yogurt is the same for...

2. A researcher wishes to determine whether there is a
difference in the average age of elementary school, high school,
and community college teachers. Teachers are randomly selected from
each group. Their ages are recorded below. Test the claim that at
least one mean is different from the others. Use α = 0.01.

The director of an alumni association wants to determine whether
there is any type of relationship between the amount of an alumni's
contribution (in dollars) and the number of years the alumnus has
been out of school. Based on the data below, compute the value of
the correlation coefficient between the number of years and the
amount of the contribution.

The director of Human Resources at a large company wishes to
determine if newly instituted training has been effective in
reducing work-related injuries. In a random sample of 100 employees
taken from the six months before this training began (group 1), she
found 15 had suffered a work-related injury. Using a random sample
of 150 employees from the six months since the training began
(group 2), she found 12 had suffered a work-related injury.
a) Find the 95% confidence interval...
