In a test of weight loss programs, 120 subjects were divided such that 40 subjects followed each of 3 diets. Each was weighed a year after starting the diet and the results are in the ANOVA table below. Use a 0.05 significance level to test the claim that the mean weight loss is the same for the different diets.

A sample of colored candies was obtained to determine the weights of different colors. The ANOVA table is shown below. It is known that the population distributions are approximately normal and the variances do not differ greatly. Use a 0.025 significance level to test the claim that the mean weight of different colored candies is the same. If the candy maker wants the different color populations to have the same mean weight, do these results suggest that the company has...

A study of 6 different weight loss programs involved 120 subjects. Each of the 6 programs had 20 subjects in it. The subjects were followed for 12 months. Weight change for each subject was recorded. We want to test the claim that the mean weight loss is the same for the 6 programs. (a) Complete the following ANOVA table with sum of squares, degrees of freedom, and mean square (Show all work): Source of Variation Sum of Squares (SS) Degrees...

Question 3 4 pts In a test of weight loss programs, 44 adults used the Atkins weight loss program. After 12 months, their mean weight loss was determined to be 2.4 lbs., with a variance of 23.6 1b2. Assuming the sample is a simple random sample obtained from a population with a normal distribution, construct a 95% confidence interval estimate of the standard deviation of the weight loss for all such subjects. Keep your numerical answers rounded to 3 decimal...

9. In a study of the effectiveness of weight-loss programs, 47 subjects who were at least 20% overweight took part in a group support program for 10 weeks. Private weighings determined each subject's weight at the beginning of the program and 6 months after the program's end. The paired I test was used to assess the significance of the average weight loss. The paper reporting the study said, "The subjects lost a significant amount of weight over time, R46-4.68, P0.01....

When 40 people use the Weight Watchers diet for one year, their mean weight loss was 3.0 pounds. Historically the standard deviation is σ = 4.9 pounds (based on data from “Comparison of the Atkins, Ornish, Weight Watchers, and Zone Diets for Weight Loss and Heart Disease Reduction,” by Dansinger, et al., Journal of the American Medical Association, Vol. 293, No. 1). Use a 0.01 significance level to test the claim that the mean weight loss is greater than 0....

The P-value for a hypothesis test is 0.079. For each of the following significance levels, decide whether the null hypothesis should be rejected. a. alphaequals0.05 b. alphaequals0.10 a. Determine whether the null hypothesis should be rejected for alphaequals0.05. A. Reject the null hypothesis because the P-value is equal to or less than the significance level. B. Do not reject the null hypothesis because the P-value is equal to or less than the significance level. C. Reject the null hypothesis because...

A diet center claims that it has the most effective weight loss program in the region. Its advertisements say, “Participants in our program lose more than 5 pounds within a month.” Six clients of this program are weighed on the first day of the diet and then one month later. Let the difference be defined as Weight on First Day of Diet minus Weight One Month Later. (You may find it useful to reference the appropriate table: z table or t table) ClientWeight on First...
