Based on all student records at Camford University, students spend an average of 6.60 hours per week playing organized sports. The population's standard deviation is 3.00 hours per week. Based on a sample of 49 students, Healthy Lifestyles Incorporated (HLI) would like to apply the central limit theorem to make various estimates.

What is the chance HLI will find a sample mean between 5.9 and 7.3 hours? (Round your z and standard error values to 2 decimal places and final answer to 4 decimal places.)

Calculate the probability that the sample mean will be between 6.2 and 7 hours. (Round your z and standard error values to 2 decimal places and final answer to 4 decimal places.)

part B A normal population has a mean of 65 and a standard deviation of 13. You select a random sample of 16.

Compute the probability the sample mean is: (Round your z values to 2 decimal places and final answers to 4 decimal places)

Greater than 67.

Less than 64.

Between 64 and 67
