A simple random sample of 14 people from a certain population have an average body mass index (BMI) and standard deviation of 30.5 and 10.64, respectively. At the 5% significance level, can we conclude that the population from which the sample is drawn has a BMI different from 35? Below is the appropriate StatCrunch output for the problem. Assume that BMI is approximately normally distributed. Choose the most appropriate portion below from the conclusion for the hypothesis test in problem twelve. (Recall the question being asked is: Can we conclude that the population from which the sample is drawn has a BMI different from 35?)
