The Fitness Today Gym recommends exercising 3 hours a week for a healthier body. Comparing health of people who do not exercise with people who exercise 3 hours a week, and those who exercise 6 hours a week, you concluded that people who exercised 6 hours a week ended up healthier than the no exercise group and the group with only 3-hour exercise. Which among the choices further reflects the conclusion? * O There is no difference between groups. O There is a difference between groups. There is no difference within groups. O All of the above.

The manager at one of the KFC restaurants in Johannesburg central randomly selected the prices of meals purchased by 20 customers on one Saturday afternoon. These prices were all tabulated in a table given below for analysis: R46 R65 R80 R72 R90 R58 R46 R47 R48 R35 R65 R56 R36 R69 R62 R50 R54 R50 R46 R48 Table 1: Prices of meals purchased by 20 Customers a) State the random variable in this scenario and give its data type b) Find the Median value and deduce its meaning c) Which meal price indicates the meal that was purchased the most? What statistical name is given to this value? d) Find the standard deviation of the 20 meal prices e) Which measure of central tendency would be best to describe this dataset? Why?
Surveys were distributed to 1,085 adults asking, “Do you enjoy shopping for clothing for yourself?” The results indicated that 51% of the females enjoyed shopping for clothing for themselves as compared to 44% of the males. The sample sizes of males and females were not provided. Suppose that the results were shown in the following table: ENJOYS SHOPPING GENDER FOR CLOTHING Male Female Total Yes 238 276 514 No 304 267 571 Total 542 543 1,085 (a) Suppose that the respondent chosen is a female. What is the probability that she does not enjoy shopping for clothing? (b) Suppose that the respondent chosen enjoys shopping for clothing. What is the probability that the individual is a male? (c) Are enjoying shopping for clothing and the gender of the individual independent? Explain.

The campus bookstore at a local university is interested in finding out whether the textbook preference and the class level (freshman, sophomore, junior, senior) of the student are associated. A random sample of 100 students is obtained, and each student in the sample is asked which textbook he or she prefers: new books, used books, or digital books. The students are also asked whether their class level is freshman, sophomore, junior, or senior. Which of the following is the appropriate test for the investigation? A one-sample tt-test for a population mean A A two-sample tt-test for a difference between means B A chi-square goodness-of-fit test C A chi-square test of homogeneity D A chi-square test of independence E

A manufacturing company that produces laminate for countertops is interested in studying the relationship between the number of hours of training that an employee receives and the number of defects per countertop produced. Ten employees are randomly selected. The number of hours of training each employee has received is recorded and the number of defects on the most recent countertop produced is determined. The results are as follows. Hours of Training Defects per Countertop 1 5 4 1 7 0 3 3 2 5 2 4 5 1 5 2 1 8 6 2 Copy Data The estimated regression line and the standard error are given. Defects per Countertop=6.717822−1.004950(Hours of Training)se=1.229787se=1.229787 Suppose a new employee has had 5 hours of training. What would be the 90% prediction interval for the number of defects per countertop? Round your answer to two decimal places.
