a magazine reports that the average bowling score for league bowlers in the united States is 157 with standard deviation 12, scores are approximately normally distributed.
what's the probability a random sample of 150 bowlers will have an average score greater than 165.
mean= 157 sd= 0.98
I worked it out by finding the z-score but the z score ended up being 8.16 which is impossible, i'm so confused please help!
