University students who drink alcohol, usually consume about 6 drinks per week. Given that about 60% of students drink alcohol, what would you predictto be the shape of the distribution of the number of cups drunk for university students (which include those who drink alcohol and those who don't)?Select one:O a. negatively skewed with scores bunched at 6 drinks per weekb.normal distribution with one peak at 6 drinks a weekleptokurtic with scores bunching around 6 drinks a weekO d. positively skewed with scores bunched at 3 drinks a week.O e. bimodal distribution with one peak at zero and another peak at about 6 drinks per weekO C.

Atlanta area animal shelters euthanize more animals per year than most other major city shelters. The following stem-and-leaf display shows the number of homeless cats and dogs that had to be euthanized each year in the Atlanta area for the period 1985-2004. Describe the distribution (shape, center, spread, unusual features). Choose the best answer for the question above: a. The distribution of the number of cats and dogs that were euthanized is unimodal, ranging from 81,100 to 90,100 euthanized. The center of the distribution is at around 85,500. b. The distribution of the number of cats and dogs that were euthanized is skewed to the right, and has several modes, with gaps in between. One mode is clustered between 87,000 and 90,000 euthanized, a second mode at 84,000, and a third mode with a cluster between 81,000 and 82,000. c.The distribution of the number of cats and dogs that were euthanized is bimodal. The upper cluster is between 89,000 and 90,000 euthanized, with a center at…
In a study conducted to examine the quality of fish after 7 days in ice storage, ten raw fish of the same kind and approximately the same size were caught and prepared for ice storage. The fish were placed in ice storage at different times after being caught. A measure of fish quality was given to each fish after 7 days in ice storage. The sample data are shown below, where "Time" is the number of hours after being caught that the fish was placed in ice storage and "Fish Quality" is the measure given to each fish after 7 days in ice storage (higher numbers mean better quality). Which variable would be considered the response variable? Fish Time: 0 0 2 3 5 6 7 9 11 12 Fish Quality 8.5 8.4 8.0 8.1 7.8 7.6 7.3 7.0 6.8 6.7 Choose the correct answer below. A.Fish Quality B.Time C.Neither variable could be considered a response variable.

How many samples or treatments are here? 490 undergraduate students at a state university in the southwestern region of the United States were surveyed. Each student in the sample was classified according to class standing (freshman, sophomore, junior, or senior) and body are category (body piercings only, tattoos only, both tattoos and body piercings, no body art). Use the data in the accompanying table to determine if there is an association between class standing and body art category. Assume that it is reasonable to regard the sample as representative of the students at this university. Use α = 0.01.

A contributor for the local newspaper is writing an article for the weekly fitness section. To prepare for the story, she conducts a study to compare the exercise habits of people who exercise in the morning to the exercise habits of people who work out in the afternoon or evening. She selects three different health centers from which to draw her samples. The 57 people she sampled who work out in the morning have a mean of 4.8 hours of exercise each week. The 56 people surveyed who exercise in the afternoon or evening have a mean of 4.2 hours of exercise each week. Assume that the weekly exercise times have a population standard deviation of 0.8 hours for people who exercise in the morning and 0.3 hours for people who exercise in the afternoon or evening. Let Population 1 be people who exercise in the morning and Population 2 be people who exercise in the afternoon or evening. Step 1 of 2 : Construct a 95% confidence interval for the true difference between the mean amounts…
