To investigate the effect of four treatments on change in body fat mass each of 74 male subjects who were over age 65 was assigned at random to one of the following four treatments: (1) placebo"growth hormone" and placebo "steroid" (denoted by P + P), (2) placebo "growth hormone" and the steroid testosterone (denoted by P + S), (3) growth hormone and placebo "steroid"(denoted by G + P), and (4) growth hormone and the steroid testosterone (denoted by G + S). The accompanying table lists data on change in body fat mass over the 26-week period following thetreatment. Carry out an F test to see whether true mean change in body fat mass differs for the four treatments if N = 74, grand total 7 = -158.3, and x = = -2.1392.

Citrus F v is a popular car rental agency that has a history of having too few cars available, so that its available cars are overdriven. The mean monthly mileage uver the years for Citrus cars has been about 1600 miles per month. Recently, though, Citrus purchased thousands of new cars, and the company claims that the average mileage of its cars is now less than in the past. To test this, a random sample of 21 recent mileages of Citrus cars was taken. The mean of these 21 mileages was 1553 miles per month, and the standard deviation was 241 miles per month. Assume that the population of recent monthly mileages of Citrus cars is normally distributed. At the 0.05 level of significance, can it be concluded that the mean recent monthly mileage, u, of Citrus cars is less than 1600 miles per month? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null…
1 of 15 > According to the World Health Organization (WHO), Body Mass Index (BMI) is a statistic that indicates the ratio of a person's weight to their body volume. The Center for Disease Control (CDC) uses the table to classify children from ages 2 to 20. Because BMI values change as children grow, the CDC uses percentiles rather than fixed values for BMI. Percentiles provide a basis of comparison for BMI over time. Weight status Percentile range Underweight Less than the 5th percentile Healthy weight 5th percentile to less than the 85th percentile Overweight Obese 85th to less than the 95th percentile Equal to or greater than the 95th percentile Based on data from WHO, a representative sample of 11-year-old females could consist of the following 15 values. 15.8, 16.1, 13.7, 15.3, 19.2, 14.7, 18.1, 16.8, 18.6, 19.9, 16.5, 17.7, 17.2, 27.0, 21.4 85th percentile: DELL 23 & 4 6 8. 9. e y i k + II .. ..
