Chapter 2, Problem 1CQQ
Cookies Refer to the accompanying frequency distribution that summarizes the numbers of chocolate chips found in each cookie in a sample of Chips Ahoy regular chocolate chip cookies (from Data Set 28 “Chocolate Chip Cookies” in Appendix B). What is the class width? Is it possible to identify the original data values?
Expert Solution & Answer
To determine
To find: The class width in the frequency distribution.
To identify: The original values in the frequency distribution.
Answer to Problem 1CQQ
The class width for each class is 3.
No, it is not possible to identify the original data values in the frequency distribution table.
Explanation of Solution
Given info:
The data shows the frequency distribution for the number of chocolate chips in each cookie from a sample of cookies.
Calculation:
Formula for finding the class width:
From the given table, the maximum data value is 32, the minimum data value is 18 and the number of classes is 5. Substitute these values in the class width formula.
Thus, the class width for each class is 3.
Justification:
No, it is impossible to identify the original data values because only the frequency distribution is given.

The club is selling Chinese fortune cookies at a price of $2 per cookie. Each cookie contains a piece of paper with a different number written on it. A random drawing will determine which number is the winner of a dinner for two at a local Chinese restaurant. The dinner is valued at $32. Since fortune cookies are donated to the club, we can ignore the cost of the cookies. The club sold 718 cookies before the drawing. Lisa bought 13 cookies. Lisa's expected earnings can be found by multiplying the value of the dinner by the probability that she will win. What are Lisa's expected earnings?
