"Mr. Z gave a test in Physics. Scores for the class are as follows: 76, 55, 73, 93, 29, 74, 57, 34, 54, and 75 out of a possible 100 points. Assume scores from this test are normally distributed.
If this set of scores is representative of all Physics classes Mr. Z has (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"
I think the following is what is meant:
