Dr. Diet launched a new diet. He argues that it will make patients lose more than 10 Ibs. over 5 months. A random sample of 25 students follow the diet for 5 months yielding an average weight loss of 4 pounds and a sample variance of 9 Ibs. Assume that the distribution of each individual's weight loss is normally distributed with unknown mean and variance. Construct a 95% confidence interval for the mean of the distribution of each individual's weight loss.
Homework Answers
Answer #1
Given: 
(Since, it is mentioned that the normal distribution is followed, Z scores are used)
Confidence interval is computed using the following formlua
Mean(X) = 4

A brochure inviting subscriptions for a new diet program states
that the participants are expected to lose at least 10 kg in five
weeks. Suppose that, from the data of the five-week weight losses
of 16 participants, the sample mean and standard deviation are
found to be 8.68 and 2.5 kg, respectively. Assume that the weight
loss is normally distributed. At 5% significance level, could the
statement in the brochure be supported on the basis of these
findings? (Write

1. A university with a high water bill is interested in
estimating the mean amount of time that students spend in the
shower each day. In a sample of 11 students, the average time was
5.33 minutes and the standard deviation was 1.33 minutes. Using
this sample information, construct a 99% confidence interval for
the mean amount of time that students spend in the shower each day.
Assume normality.

(1 point) A recent study in the Journal of the American Medical
Association reported the results of an experiment where 40
overweight individuals followed the Weight Watchers diet for one
year. Their weight changes at the end of the year had a mean of
?¯=3.1x¯=3.1 kg with a standard deviation of ?=4.7s=4.7 kg. We want
to use this data to test the claim that the diet has an effect,
that is, that the weight change is higher than 0.
