Question
A brochure inviting subscriptions for a new diet program states that the participants
are expected to lose over 22 pounds in five weeks. The standard deviation of the
amount of weight loss is assumed to be 10.2 pounds. The data based on the five-
week losses of randomly selected 56 participants gives a sample mean of 23.5
pounds. Can you perform a hypothesis test based on this information?
O No. Even if the sample is a random sample and the sample size large, the
population must be normally distributes to perform a hypothesis test.
O Yes. It is stated that the amount of weight loss are normally distributed and the
sample is a random sample.
No. Even if the sample is a random sample, the population is not normal and the
sample is smal. Also the boxplot of the data looks very skewed.
O Yes. The sample is a random sample and even though the population is not
normal but the sample size is large enough.
