If this set of scores is representative of all Physics classes have (in other words, with the same mean and same standard deviation), on average what percent of students pass this test? (Passing is 60% minimum.) Use technology or Standard Normal table to find probabilities and show all your reasoning to answer the question. List z-score and percent probability to 2 decimal places or decimal probability to 4 decimal places.
Here are the numbers-->76, 55, 73, 93, 29, 74, 57, 34, 54, 75 out of a possible 100 points.
Here are the Mean, Median, and Standard Deviation-->
Mean=62
Median=65
Standard Deviation=20
Thanks so much for your help.
