- A researcher is interested in studying the effect that the amount of fat in the diet and amount of exercise has on the mental acuity of middle-aged women. The researcher used three different treatment levels for the diet and two levels for the exercise. The results of the acuity test for the subjects in the different treatment levels are shown below.

Perform a Two-way analysis of variance (ANOVA) and report the results using correct APA style; report whether significance was found for Factor A, Factor B, and/or an interaction between Factors A and B was found.
If the test statistic is significant, run a post hoc test to determine between what groups significance was found.
Report an effect size for all significant results.

A health researcher was interested in comparing three methods of
weight loss: low-calorie diet, low-fat diet, and high-exercise
regimen. He selected 15 moderately overnight subjects and randomly
assigned 5 to each weight-loss program. The following weight
reductions (in pounds) were observed after a one-month period:
Low-fat diet: 7,6,8,8,6 low Calorie diet: 7,7,5,4,5 high exercise:
7,8,7,9,8
a) Test the null hypothesis that the extent of weight reduction
does not differ by type of weight-loss program. (Set α=.01 level)
(10 points) b)...

2. A researcher is interested in testing the relationship
between the amount of fat in one's diet and the development of
cancer (of any type).
a. What is the research hypothesis? What is the null
hypothesis?
b. How will the researcher determine whether or not there is a
relationship between dietary fat and cancer? What steps will the
researcher take?
c. Assume that the researcher made an error of the second type
(i.e., a type II error). What did the...

Researchers studying the effect of diet on growth would like to
know if a vegetarian diet affects the height of a child. Twelve
students are randomly selected that are all 6-years old. The
average height of these kids is 42.5 inches with a standard
deviation of 3.8 inches. The average height of all 6-year old kids
is found to be 45.75 inches. Conduct a hypothesis test to determine
if there is overwhelming evidence at alpha = .05 that 6-year old...

A researcher is interested in determining if there is a
difference in the amount of time babies pay attention to other
babies and to adults. The researcher takes a group of 26
babies and randomly assigns them to two groups (there are 13 babies
in each group). In one group, babies watch a video of
other babies and in the other group, babies watch a video of
adults. The researcher records how long each baby pays
attention to the video. He finds that babies...

A researcher at the Annenberg School of Communication is
interested in studying the use of smartphones among young adults.
She wants to know the average amount of time that college students
in the United States hold a smartphone in their hand each day. The
researcher obtains data for one day from a random sample of 25
college students (who own smartphones). She installs an app that
registers whenever the smartphone is being held and the screen is
on. The sample...
