Eight people were on a special diet to lose weight. We are testing to see if the diet actually works. We are going to do a Wilcoxon test. Please calculate the Wilcoxon T statistic. The critical value is 3. It is a two-tailed test with α = .05. Then come to a conclusion about the effectiveness of the diet. The data is:

                Before: 253         196         155         234         133         181         295         235

                After:     190         144         125         180         115         191         160         232

The changes in weight during three months for six people on a diet were 10,12, 14, 16, 17, and −2 pounds. Use the sign test to find and interpret the​ P-value for testing that the probability that the weight difference is positive equals 0.50 against the alternative hypothesis that it is greater than 0.50. 1) Identify the correct null and alternative hypotheses. I know that the correct answer for this part is: H0 : p = 0.50 Ha : p...

On a television show, eight contestants try to lose the highest percentage of weight in order to win a cash prize. As part of the show, the contestants are timed as they run an obstacle course. The table shows the times (in seconds) of the contestants at the beginning of the season and at the end of the season. At α=0.05 is there enough evidence to support the claim that the contestants' times have changed? Assume the samples are random...

Sixteen laboratory animals were fed a special diet from birth through age 12 weeks. Their weight gain (in grams) were as follows: 63 68 79 65 64 63 65 64 76 74 66 66 67 73 69 76 Can we conclude from these data that the diet results in a mean weight gain of less than 70 grams? Let α = 0.05. Note: There are two possible ways to analyze this data. Use the statistical procedure that makes use of...

Weight Loss in Men Many polls have asked people whether they are trying to lose weight. A Gallup poll in November 2008 showed that 22% of men said they were seriously trying to lose weight. In 2006, 24% of men (with the same average weight of 194 pounds as the men polled in 2008) said they were seriously trying to lose weight. Assume that both samples contained 500 men. Determine whether the difference in proportions is significant at the 0.05...

When 41 people are used the Weight Watchers diet for one year, their weight losses had a standard deviation of 4.9lb. Use a 0.01 significance level to test the claim that the amounts of weight loss have a standard deviation equal to 6.0lb, which appears to be the standard deviation for the amounts of weight loss with the Zone diet. Write your assumptions before you conduct hypothesis testing.

A study of 50 people who were not on a diet showed that they consumed an average of 2200 calories in a day, with a standard deviation of 400 calories per day. For 40 people who were on a diet, they consumed an average of 2100 calories per day, with a standard deviation of 250 calories per day. Assume both populations are normally distributed. a) Test the claim that people on a diet consume fewer calories. b) Test the claim...
