[Statistics: Confidence Intervals and Hypothesis Testing] How do you solve this, will upvote if done quickly The water diet requires you to drink two cups of water every half-hour from when you get up until you go tobed, but otherwise allows you to eat whatever you like. Four adult volunteers agree to test the diet. They areweighed prior to beginning the diet and after six weeks on the diet. The weights (in pounds) arePerson124Weight before the180125240150dietWeight after six170130215152weeksFor the population of all adults, assume that the weight loss after six weeks on the diet (weight beforebeginning the diet minus weight after six weeks on the diet) is Normally distributed with mean u.Find a 95% confidence interval for u based on these data. Finally, provide numerical value of UpperConfidence Limit (UCL). Round your final answer to 4 decimal places.

Question Help In a random sample of n = 200 patients, the proportion cured by a new drug was p = 120/200 = 0.6. We would like to determine with 90% confidence whether this provides sufficient evidence that, in the long run, the cure rate of the new drug would be higher than the 51% cure rate of the old drug. That is, we want to: Test Ho: p = 0.51 New drug is no better than the old drug. Versus Ha: p> 0.51 New drug is better than the old drug. Use all digits showing on your calculator in your intermediate calculations but show only the indicated number of digits to the right of the decimal point in your final answer. (a) Critical value from the z table: (b) Test statistic: (c)Conclusion: O A. Fail to reject Ho. Sample does not provide enough evidence to say that the new drug is better than the old. g O B. Reject Ho with 90% confidence and conclude that the new drug is better than the old. (d) p-value: Because the p-value is less than 0.01, the sample provides strong evidence that the…

Analyze and write about statistical study. Grapefruit Lowers Weight, Fights Cancer Studies find benefits to eating the citrusBy Kathleen DohenyWEDNESDAY, Aug. 25 (HealthDayNews) -- A grapefruit or two a day, along with a healthy diet, could help shrink widening waistlines. This finding comes from one of several studies on the benefits of citrus fruits presented Wednesday at the annual meeting of the American Chemical Society in Philadelphia.The so-called grapefruit diet -- which advocates mostly eating grapefruit with some protein -- has been popular on and off for weight loss for years, said Dr. Ken Fujioka, director of nutrition and metabolism research at the Scripps Clinic in San Diego and lead author of a study evaluating grapefruit for weight loss. Most nutrition experts have deemed the grapefruit-and-protein regimen unhealthy, and Fujioka is not advocating any return to such a strict diet. However, his findings do suggest that a grapefruit or two each day, added to a balanced…
