A nutritionist wants to know if there is a difference in blood pressure if a person follows a Mediterranean diet. The nutritionist obtains participants’ blood pressure before and after the diet program. What would be the most appropriate statistical test to determine whether there is a significant reduction in blood pressure?
Solutions
Expert Solution
Median test or sign test is appropriate for this situation.
For this problem assume X be the blood pressure before diet program and Y be the blood pressure after diet program.

A nutritionist is interested in the effect of eating a
vegetarian diet on blood pressure. Specifically, she is interested
in determining if vegetarians have lower systolic blood pressure
readings than omnivores. A sample of eight vegetarians and eight
omnivores were randomly selected from a normal population to
participate in the study. The systolic blood pressure levels of
each group were measured and the results are recorded in the
following table. use an alpha level of α = .05.
Systolic Blood...

A researcher wants to know if calcium is an effective treatment
for lowering blood pressure. He assigns one randomly chosen group
of subjects to take calcium supplements; the other group will get a
placebo. At the end of the treatment period, he measures the
difference in blood pressure. The 50 members of the calcium group
had blood pressure lowered by an average of 25 points with standard
deviation 10 points. The 50 members of the placebo group had blood
pressure...

2. Blood pressure is independent of the blood group. We want to
know, if the distributions attending to the blood group, in three
referred samples attending to the type of blood pressure, they are
distributed in the same way. To this end, a sample of 1500 subjects
was collected and their blood group was determined and blood
pressure was taken, classifying it as low, normal, and high.
Obtaining the following results:

A professor wants to
know whether or not there is a difference in comprehension of a lab
assignment among students depending on if the instructions are
given all in text, or if they are given primarily with visual
illustrations. She randomly divides her class into two groups of
15, gives one group instructions in text and the second group
instructions with visual illustrations. The following data
summarizes the scores the students received on a test given after
the lab. Let...
