1. We have sent out everyone in a large introductory course to check whether people use seat belts. Each student has been told to look at 100 cars and count the number of people wearing seat belts. The number found by any given student is considered that student’s score. The mean score for the class is 44, with a standard deviation of 7. a. Diagram this distribution, assuming that the counts are normally distributed.

2. A set of reading scores for fourth-grade children has a mean of 25 and a standard deviation of 5. A set of scores for ninth-grade children has a mean of 30 and a standard deviation of 10. Assume that the distributions are normal. a. Draw a rough sketch of these data, putting both groups in the same figure.

Can I get a step by step process of how to graph this in excel for both questions?

Solution

i think there is something missing in the ques.
