QUESTION 121 POINT
A computer chip manufacturer is looking for ways to increase its profit margin on the CPUs it produces. As part of their
analysis, they randomly select 12 CPU orders and record the speed of the chip (in GHz). The results are given below.
Determine the class width for a grouped data frequency table with 6 classes based on these values.
1.1, 1.1, 1.3, 1.4, 1.4, 1.7, 1.8, 2.2, 2.5, 2.7, 3.1, 3.6
Provide your answer below:

Answer 1

Explanation:

To determine the class width for a grouped data frequency table with 6 classes, we need to find the range of the data and divide it by the number of classes.

The given CPU speeds are: 1.1, 1.1, 1.3, 1.4, 1.4, 1.7, 1.8, 2.2, 2.5, 2.7, 3.1, 3.6

Step 1: Find the range The range is the difference between the highest and the lowest values in the data set.

In this case, the highest value is 3.6 GHz and the lowest value is 1.1 GHz. Range = 3.6 - 1.1 = 2.5 GHz Step

2: Divide the range by the number of classes To find the class width, divide the range by the number of classes. In this case, we have 6 classes.

Class width = Range / Number of classes = 2.5 / 6 Using division, we find that the class width is approximately 0.42 GHz.

the class width for the grouped data frequency table with 6 classes is approximately 0.42 GHz.
