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. Suppose for a sample of size 15, the test statistic value is reported as t= - 1.29. For each of the following alternative hypotheses, find the appropriate p-value. Ho : µ = µo Ha :H 1.
