Document Summary

You may use calculators and one page of notes. Do not spend too much time on any one problem. Put a box around the nal answer to a question. There are more questions on the back: six parents had the following numbers of children: 1, 2, 2, 3, 7, 3 . (a) (8 pts. ) Determine the sample mean and median number of children. (b) (6 pts. ) Determine the sample standard deviation. (c) (6 pts. ) For the bins (bases of rectangles), use intervals [. 5, 1. 5), [1. 5, 2. 5), [2. 5, 3. 5), etc. Indicate the scale on the y-axis: a sample space is the union of events a, b, c. suppose the events b and c are mutually exclusive; A and b are independent and p(ab) = . 12 ; Compute the mean and standard deviation of x: (a) in her morning commute, a professor passes through an intersection at which the tra c light is red with probability . 3 .
