A student at a large university suspects Mr. Harsh is grading his statistics students too harshly. The student determines that over the past 2 years students in all sections of statistics (taught by other teachers) received grades of A, B, C, D, or F in the following proportions: A: 0.20; B: 0.30; C: 0.30; D: 0.10; and F: 0.10. The student then takes an SRS of 90 students who took statistics with Mr. Harsh in the past 2 years and gathers the following information: Grade Number of students B 26 12 28 15 The student performs the appropriate y2 procedure to test the hypothesis that the teacher's grade distribution is different from the other teachers Which of the following expressions represents the expected count of the grade category D? O (0.10)(90) O 1s? 90 (15-9) O (0.10)(15)

The following scores are from an ordinal measurement: 1, 2, 2, 4, 5, 6, 7, 8, 9, 10 Please calculate all of the measures of variation that are appropriate.
I had to find the 20th percentile with the following data. 0, 1, 2, 2, 2, 3, 4, 4, 4, 8..... My first answer was 1.8. I got that by doing .20(10) = 1.8. This answer was wrong. I rounded up to 2 and that was also wrong. Was I supposed to indentify all the numbers that would be categorized in the 20th percentile?
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 6060 people she sampled who work out in the morning have a mean of 3.33.3 hours of exercise each week. The 4747 people surveyed who exercise in the afternoon or evening have a mean of 3.43.4 hours of exercise each week. Assume that the weekly exercise times have a population standard deviation of 0.40.4 hours for people who exercise in the morning and 0.70.7 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 99%99% confidence interval for the true difference…

Of course, that is incorrect. What is the mean score for all ninth graders in the city? Round to one decimal place. mean of all ninth grader's scores =
The state Government gives grants to low-income undergraduate students. According to the National Postsecondary Student Aid Study conducted by the U.S. Department of Education in 2008, the average Pell grant award for 2007-2008 was $2,600. We wonder if the mean amount is different this year for Pell grant recipients at San Jose State University. Suppose that we randomly select 50 Pell grant recipients from San Jose State University. For these 50 students, the mean Pell grant award is $2,450 with a standard deviation of $600. Let µ = the mean amount of Pell grant awards received by San Jose State University Pell grant recipients this year. We test the hypotheses: H0: μ = 2,600 , Ha: μ ≠ 2,600. The sample size is greater than 30, so a t-model is a good fit for the sampling distribution. What is the t-test statistic? What is the P-value?

The accompanying table gives amounts of arsenic in samples of brown rice from three different states. The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Do the amounts of arsenic appear to be different in the different states? Given that the amounts of arsenic in the samples from Texas have the highest mean, can we conclude that brown rice from Texas poses the greatest health problem? Click the icon to view the data.
