The average grade in a statistics course has been 76 with a standard deviation of 11. If a random sample of 56 is selected from this population, what is the probability that the average grade is more than 80? Use Appendix B.1 for the z-values. (Round your z-value to 2 decimal places and the final answer to 4 decimal places.) Probability
