GlenBluss Community College has a population mean GPA is 2.82 with population standard deviation of 1.07 for all students who have ever attended the college. Find the probability a student at random will have a GPA over 3.24. __________Round to 4 decimal places.If 5 students are chosen at random, what is the probability their mean GPA will be more than 3.24?__________% Round to the nearest whole percent.

How do I do this problem?

A successful basketball player has a height of 6 feet 6 ​inches, or 198 cm. Based on statistics from a data​ set, his height converts to the z score of 3.38. How many standard deviations is his height above the​ mean?   The​ player's height is _____standard​ deviation(s) above the mean. ​(Round to two decimal places as​ needed.)

A population has a mean = 85 and a standard deviation a=22. Find the mean and standard deviation of a sampling distribution of sample means with sample size n=230. H₂= (Simplify your answer.) 0

Assume you have taken 125 samples of size 81 each from a population. The population variance is 64. What is the standard deviation of each (and every) sample mean? 0.5 0.89 9 8

A population has a mean µ = 81 and a standard deviation o = 36. Find the mean and standard deviation of a sampling distribution of sample means with sample size n= 81. (Simplify your answer.) o; = (Simplify your answer.) O- =

Scores on an exam were normally distributed. Ten percent of the scores were below 60.0 and 80% were below 81. Find the mean and standard deviation of the scores. (Round the final answer for the mean to two decimal places.) (Round the final answer for the standard deviation to four decimal places.)
