# Question

Using the data for ENGG in Appendix D perform the following:

(a) Calculate the variance and the standard deviation for ENGG.

(b) These measures should be greater than the corresponding measures on GPA. Can you explain why this should be? (We will come back to this later in Chapter 12, but see if you can figure it out.)

The mean of the data used in Exercise 5.1 is 46.57. Suppose that we had an additional subject who had a score of 46.57. Recalculate the variance for these data. (You can build on the intermediate steps used in Exercise 5.1.) ...Calculate the range, the variance, and the standard deviation for the data that Katz et al. collected on SAT performance after reading the passage. In Exercise 5.1, what percentage of the scores fall within two standard deviations from the mean? 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 ...Suppose that we are collecting a large data set on emotional reactivity in adults. Assume that for most adults emotional reactivity is normally distributed with a mean of 100 and a standard deviation of 10. But for people ...Post your question
