Data was collected for 287 randomly selected 10 minute intervals. For each ten-minute interval, the number of people entering the atrium of a large mall were recorded. The data is summarized in the histogram below.
What is the class width for
this histogram? Note: Each class contains its lower class limit,
but not its upper-class limit.
Class width = ?
Homework Answers
since Class width =difference between lower or upper limit of two consecutive classes
class width =190-185 =5

8. A student scores 56 on a geography test and 285 on a mathematics test. The geography test has a mean of 80 and a standard deviation of 20. The mathematics test has a mean of 300 and a standard deviation of 10. If the data for both tests are normally distributed, on which test did the student score better relative to the other students in each class?

First, the table has approximately 10 (options, class
intervals, or interval widths)
The width of each interval is a relatively (wide, simple, or
complex) number.
The bottom score in each class interval is a (reflection,
multiple, or factor) of the width.
In which interval would a score of 29.6 fall? (20-29, there is
no interval for this number, or 30-39)
In which interval would a score of 19.4 fall? (There is no
