Keep in mind that certain distributions, such as exam scores or some physical characteristics for specific age and gender groups, naturally follow a normal shape. Other distributions are naturally skewed left or have low outliers if there tend to be relatively few values that are unusually low compared to the rest. Yet other distributions are naturally skewed right or have high outliers if there tend to be relatively few values that are unusually high compared to the rest. Decide if each of the following variables is most likely to have a shape that is approximately normal, or skewed left/low outliers, or skewed right/high outliers:
a. Number of minutes that students spend on the computer on a given day
b. Number of minutes that students spend on the phone on a given day
c. Verbal SAT scores
d. Number of cigarettes smoked in a day by a large group of students who smoke
e. Amount of cash carried by students
f. Heights of students' fathers
g. Ages of students' mothers
h. Number of hours that students slept on a given night in a large group of students that includes a few who got little or no sleep
