A sample of blood pressure measurements is taken from a data set and those values (mm Hg) are listed below. The values are matched so that subjects each have systolic and diastolic measurements. Find the mean and median for each of the two samples and then compare the two sets of results. Are the measures of center the best statistics to use with these data? What else might be better?

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. The percentile score is the proportion of students who would score LESS THAN OR EQUAL TO the score for the individual student. Compute the percentile scores for the five scores.

A random sample of 10,000 bottles of cola was taken to see whether the mean weight was 16 fluid ounces, as marked on the container. The null hypothesis is that the population mean is 16 ounces. Use the read-out below to test the hypothesis that the colas do not have a population mean of 16 fluid ounces. You do not have to do any calculations; just interpret the given data clearly and thoroughly in the context of the problem. | One-Sample T: ounces Test of u = 16 vs = 16 Variable Mean StDev SE Mean 95 CI T P ounces 10000 15.9988 0.0985 0.0010 (15.9969, 16.0007) -1.21 0.225
For each problem, you must state the hypotheses, calculate the test statistic, and explain your decision. The following table reports the relationship between class standing and political orientation for a random sample of 267 college students. a. The table is constructed assuming that class standing is the independent variable. Please add %s in the appropriate position (columns or rows) to describe the pattern of the relationship. b. Is there a statistically significant relationship between these variables?

Mary is running for mayor. She wants to know if she has a chance to win, so she collects a random sample of 40 citizens to see if they are going to vote for her of her opponent, Henry. Out of the 40 citizens who were asked, 24 said they were voting for Henry and the other 16 said they were voting for Mary. Using this data test H0: p=.5 vs. Ha: p>.5, where p is the true proportion of people, who will vote for Mary in the population (i.e., the entire town)? Find the p-value of this test, and what is your conclusion if the test is performed at the a=.5 level?
