A simple random sample of 16 adults drawn from a certain population of adults yielded a mean weight of 63kg. Assume that weights in the population are approximately normally distributed with a variance of 49. Do the sample data provide sufficient evidence for us to conclude that the mean weight for the population is less than 70 kg? Let the probability of committing a type I error be .01. 1. Write the hypotheses, indicate the claim 2. find the critical...
