2. The average score of all golfers for a particular course has a mean of 75 and a standard deviation of 4.5. Suppose we going to randomly select 81 golfers and obtain the mean of their scores. We want to know the probability that the average score of the 81 golfers exceeds 76. What would you use on the calculator to find this probability? You do not need to calculate the probability. Just tell me what you would pick from the DISTR list (2nd, Vars) to find it.

Question 1 The average math SAT score is 511with a standard deviation of 119. A particular high school claims that its students have unusually high math SAT scores. A random sample of 50 students from this school was selected, and the mean math SAT score was 555. Is the high school justified in its claim? Explain. ▼ Pick one No Yes because the z-score (what is the z score) (?) is ▼ pick one not unusual unusual since it ▼...
