Answer:
The new values are as follows:
Mean: 134
Median: 129
Mode: 121
Range=45
Standard Deviation=3.6
Step-by-step explanation:
When a k real number is added to all the elements of the dataset, the new measures of center (mean, median, and mode) are simply found by adding the value k to the previous values. Thus
Here is 109 and k is 25 thus
Similarly
Here is 104 and k is 25 thus
Also
Here is 96 and k is 25 thus
When a k real number is added to all the elements of the dataset, the new measures of variation (range and standard deviation) remain the same thus.
Similarly
So the new values of mean, median, mode, range, and standard deviation are 134, 129, 121, 45, and 3.6 respectively.
