Question

Maximum Wind Speeds The data show the maximum wind speeds in miles per hour recorded for 40 states. Construct a frequency distribution using 7 classes. $$ \begin{array}{ccccc}{59} & {78} & {62} & {72} & {67} \\ {76} & {92} & {77} & {64} & {83} \\ {64} & {70} & {67} & {75} & {75} \\ {78} & {75} & {71} & {72} & {93} \\ {68} & {69} & {76} & {72} & {85} \\ {64} & {70} & {77} & {74} & {72} \\ {53} & {67} & {48} & {76} & {59} \\ {87} & {53} & {77} & {70} & {63}\end{array} $$

Step 1

The minimum value is 48, and the maximum value is 93. So, the range is 93 - 48 = 45. Step 2: Determine the class width. Since we want 7 classes, we can divide the range by 7: 45 / 7 ≈ 6.4. We'll round up to the nearest whole number, so the class width is 7. Step Show more…
