Expert Solution

To determine

**a)**

**To Construct:**

A frequency distribution.

Set *k* = 10, R = 92 – 5 = 87, so we can round off interval size to i = 10. The first interval will be 0-9, to include the low score of 5, and the highest interval will be 90–99.

Score | Frequency |

0-9 | 3 |

1... |

Expert Solution

To determine

**b)**

**To find:**

The midpoints of the class intervals.

Expert Solution

To determine

**c)**
