Two psychologists surveyed 587 children in grades 4, 5 and 6 in elementary schools in Michigan. They stratified their sample drawing roughly 1/3 from rural, 1/3 from suburban and 1/3 from urbanschools. Among other questions they asked students whether their primary goal was to get good grades, to be popular, or to be good at sports. One question of interest was whether boys and girls at thisage had similar goals.GradesPopularSportsBoy1226780Total269Girl15113433318Total273201113587Round answers to two places after the decimal:Of the boys in grades 4, 5 and 6 in elementary schools in Michigan, what proportion have as primary goal to be good at sports?Of the girls in grades 4, 5 and 6 in elementary schools in Michigan, what proportion have as primary goal to be good at sports?Among the students in grades 4, 5 and 6 in elementary schools in Michigan who have as primary goal to be good at sports, what is the proportion are girls? ✓

In 1955, Life Magazine reported that a 25-year-old mother of three worked (on average) an 80 hour week. Recently, many groups have been studying whether or not the women's movement has, in fact, resulted in an increase in the average work week for women (combining employment and at-home work). Suppose a study was done to determine if the average work week has increased. 77 women were surveyed with the following results. The sample average was 83; the sample standard deviation was 1o. Does it appear that the average work week has increased for women at the 5% level? Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)

The President of the University of Michigan would like to know more about students on campus. He conducts a survey of 173 randomly selected students that is representative of the entire student body. He finds that 53 of 173 sampled students are Health Science majors. He also collects data on student's majors by race/ethnicity and gets the data below. Health Science Student Ethnicity yes no total African American 5 16 21 Asian/Pacific Islander 3 17 20 Caucasian 42 58 100 Hispanic 2 17 19 Other 1 12 13 Total 53 120 173 a) The President is interested in the association between race/ethnicity and major. State the null and alternative hypothesis for evaluating this. b) How many students would you expect to be Hispanic health science majors if race/ethnicity and major are independent of each other? c) You find that the chi-squared test statistic works out to be 15.6748 with a P-value equal to .003488.…

Below are the data from the study described in lecture about assessing whether Beagles or German Shepherds Dogs dig more holes. Once again, my buddy Mike hypothesizes that Beagles will dig more holes than Shepherds. Ten of each dog species are randomly assigned to fresh backyards. Mike goes to work and counts the number of holes dug in each yard when he gets home. As expected, one of the Beagles escaped, so that Beagle's score was eliminated from the data (i.e., n = 10 for the Shepherds, but n = 9 for the %3D Beagles). Go through the steps of hypothesis testing and evaluate Mike's hypothesis, using alpha = .05. Beagles GSD |12 7 10 1 6 4 8 1 14 1 H n ON

The sample data below show the number of companies providing health insurance for small, medium, and large companies. For the purposes of this study, small companies are companies that have fewer than 100 employees. Medium-sized companies have 100 to 999 employees, and large companies have 1000 or more employees. The questionnaire sent to employees asked whether or not the employee had health insurance and then asked the enployee to indicate the size of the company.

Inspired by the example about how background music influences choice of entrée at a restaurant, a statistics student decided to investigate other ways to influence a person's behavior. Using 60 volunteers, she randomly assigned 20 volunteers to get a "red" survey, 20 volunteers to get a "blue" survey, and 20 volunteers to get a control survey. The first three questions on each survey were the same, but the fourth and fifth questions were different. For example, the fourth question on the "red" survey was "When you think of the color red, what do you think about?" On the blue survey, the question replaced red with blue. On the control survey, the last two questions were not about color. As a reward, each volunteer was allowed to choose a chocolate candy in a red wrapper or a chocolate candy in a blue wrapper. The table shows the result of the experiment. We want to test Ho: The distribution of candy choice is the same for subjects like these who receive the red survey, the blue survey,…
