A study was conducted to determine the effectiveness of a diet program in reducing weight of obeys people. Eight randomly selected patients were put on this diet and the amount of weight losses (in pounds) were recorded. Suppose the sample mean and the sample standard deviation of weight losses were 38 and 4.598136 pounds, respectively. Construct a 90% confidence interval for the average weight loss and based on the confidence interval constructed determine if you would expect to see an...

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...

Without any changes in their diet a person has been loosing weight and their feces have become fatty. The medical diagnosis is "a condition limiting the production of bile". Why do you think inadequate bile leads to the symptoms of weight loss and fatty feces? Your answer must discuss the role of bile in fat digestion.

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        ...

Question 6 options: In a study of n=76 subjects that were placed on a low-fat diet, their sample mean weight loss was 2.2 kg. with a sample standard deviation of 6.1 kg. What is the test statistic for testing the mean weight loss is GREATER than 0? Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 27 is entered as 27.00, 3.5 is entered as 3.50, 0.3750 is entered as 0.38 | |...

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...

A cylindrical beaker of height 0.100 m and negligible weight is filled to the brim with a fluid of density ρ = 890 kg/m3 . When the beaker is placed on a scale, its weight is measured to be 1.00 N .(Figure 1) A ball of density ρb = 5000 kg/m3 and volume V = 60.0 cm3 is then submerged in the fluid so that some of the fluid spills over the side of the beaker. The ball is held...
