Answer

Explanation:

Step1: Determine class intervals

The lower - class limit is 70 seconds and class width is 40 seconds. The class intervals are 70 - 109, 110 - 149, 150 - 189, 190 - 229, 230 - 269.

Step2: Count frequencies

For the class 70 - 109: Count the number of data values in the range. The values 79, 91, 70, 84 in the data set fall in this range. The frequency is 4. For the class 110 - 149: The values 110, 131, 120, 120, 130, 130, 121, 102, 140, 138, 110, 140, 140, 110, 120, 109, 102, 109, 100, 137, 142, 100, 124 fall in this range. The frequency is 23. For the class 150 - 189: The values 150, 160, 163, 186, 171 fall in this range. The frequency is 5. For the class 190 - 229: The value 199 falls in this range. The frequency is 1. For the class 230 - 269: The values 253, 231, 250 fall in this range. The frequency is 3.

Service Time (seconds) Frequency
70 - 109 4
110 - 149 23
150 - 189 5
190 - 229 1
230 - 269 3

Answer:

Service Time (seconds) Frequency
70 - 109 4
110 - 149 23
150 - 189 5
190 - 229 1
230 - 269 3
