The population's standard deviation is 3.20 hours per week. Based on a sample of 144 students, Healthy Lifestyles Incorporated (HLI) would like to apply the central limit theorem to make various estimates. (a)Compute the standard error of the sample mean. (Round your answer to 2 decimal places.) Standard error (b)What is the chance HLI will find a sample mean between 5.3 and 7.3 hours? (Round z value to 2 decimal places. Round your answer to 4 decimal places.) Chance- (c) Calculate the probability that the sample mean will be between 5.9 and 6.7 hours. (Round z value to 2 decimal places. Round your answer to 4 decimal places.) Probability
