ASSIMILATION: Riley is a music DJ. So far, her average playing time per day is 5 hours, with a standard deviation of 1 hour. What is the probability that, on the next 30 days, her average playing time is less than 4.5 hours? 1. List the given information. 2. Determine the mean of the sampling distribution of the sample mean. 3. Compute for the standard deviation of the sampling distribution of the sample mean. 4. Solve for the z-score of X in the sampling distribution. 5. Use the z-table to solve the probability. 6. Conclusion.
