A photographer is interested in whether there is a difference in the proportions of adults and children who like to take pictures. In a survey of 310 randomly selected adults and 270 randomly selected children, 219 adults and 215 children said they like to take pictures.
a) Define Population 1 and Population 2.
b) Define the parameter of interest.
c) Name the distribution required to calculate confidence intervals. (Check the relevant criteria.)
d) Construct a 90% confidence interval for the true difference in proportions.
e) Interpret your confidence interval.
f) Is there a difference in the proportions (at a 90% CL)?

A political scientist is interested in the question of whether
or not there is a difference between Republicans and Democrats when
it comes to their involvement in voluntary associations. Using a
25-point scale to measure involvement in voluntary associations,
and collecting information from a random sample of 17 Republicans
and 12 Democrats, the political scientist discovers the
following:
Republicans: Mean of 12.56, standard
deviation of 3.77
Democrats: Mean of 16.43, standard
deviation of 4.21
Test the null hypothesis at the...

A researcher is interested in whether or not there is a
difference in student’s performance based on the study methods they
use. Participants are assigned one of three different study methods
(read the text and re-read it, read and answer prepared questions,
and read then create your own questions). There are 6 people in
each group and the researcher measures the participants’
performance on a test. Perform a hypothesis test and show all four
steps. Hints: Use a two tailed...

We are interested in studying whether there is a difference in
the time it takes for patients to recover after surgery for two
given hospitals. A simple random sample of cardiac surgery patients
were taken from each hospital. The results were summarized in the
table below. It shows the hospital one attended (Hospital A vs
Hospital B), and the average length of stay (measured in days) for
patients after cardiac surgery.
