Answer to Problem 98E
With all data values, Range = 52
After removing 120 = 36
Explanation of Solution
Given:
71 | 104 | 76 | 88 | 78 | 71 | 68 | 86 | 70 | 90 |
74 | 76 | 69 | 68 | 88 | 96 | 68 | 82 | 120 |
Formula used:
Calculation:
With all the data values:
After removing the 120 from the data values:
(b)
To interpret the range value of given data.
(b)
Explanation of Solution
The range is the difference between lowest and highest value of the dataset, which shows that all the data values falls within 52 values or between the highest and lowest values.
Since the 120 was removed due to the medical issues, then the range of the remaining data becomes 36 and that means the normal range of pulse rate is 36 and which indicates that normal pulse rate falls between 68 to 104.
