Question

Weight Loss ? A weight loss program claims that program participants have a mean weight loss of at least 10 pounds after one month. You work for a medical association and are asked to test this claim. A random sample of 30 program participants and their weight losses (in pounds) after one month is listed below. At a = 0.03, do you have enough evidence to reject the program's claim?

Answer 1

Put a two litre water bottle as well as a glass on your desk every morning. Get through it simply by lunch, and do the same inside afternoon. You’ll exercise better in addition to recover faster if you’re hydrated. I drink some water whenever someone asks me a stupid question or sends a dumb email... find something that works available for you!

Answer 2

From your data, the mean (xbar) = 9.78 lbs and std dev (s) = 2.36 lbs., and n = 30



The hypotheses are H0: u = 10 and Ha: u < 10 (u0 = 10, the hypothesized mean weight loss).



The test statistic is

z = (xbar - u0)/(s/sqrt(n)) = (9.78 - 10) / (2.36/sqrt(30))



z = -0.51



Using α = 0.03, the z critical value is -1.88. Since the test statistics z = -0.51 is less than -1.88, you should not reject the null hypothesis at the 0.03 level (97% confidence) and you can conclude that you don't have enough evidence to reject the hypothesis that people lose 10 lbs per month on average.
