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…
A statistical program is recommended. The Condé Nast Traveler Gold List provides ratings for the top 20 small cruise ships. The data shown below are the scores each ship received based upon the results from Condé Nast Traveler's Annual Readers' Choice Survey. Each score represents the percentage of respondents who rated a ship as excellent or very good on several criteria, including Shore Excursions and Food/Dining. An overall score was also reported and used to rank the ships. The highest ranked ship, the Seabourn Odyssey, has an overall score of 94.4, the highest component of which is 97.8 for Food/Dining.

A vaccine to prevent a severe virus was given to children within the first year of life as part of a drug study. The study reported that of the 3456bchildren randomly assigned the vaccine, 58 got the virus. Of the 1606 children randomly assigned the placebo, 46 got the virus. a. Find the sample percentage of children who caught the virus in each group. Is the sample percentage lower for the vaccine group, as investigators hoped? b. Determine whether the vaccine is effective in reducing the chance of catching the virus, using a significance level of 0.01.The first few steps of the hypothesis-testing procedure are given. Complete the procedure.
The NAEP music assessment scores for eighth grade students are approximately N (150, 35). Find the z-scores by standardizing the following scores: 150, 140, 100, 180, and 230.

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…
