Answer:

The range will change

Explanation:

Here, we want to know the part of the data that will be affected

Firstly, we have to understand that the mean will be left unchanged

The mean is the sum of the numbers divided by the count of the numbers;

(98 + 96 + 98 + 134 + 99)/5 is same as (98 + 96 + 98 + 134 + 99 + 93 + 117) = 105

The median will be the same

before the addition of the two new numbers;

96,98,98,99, 134

The median is 98

adding the two;

93,96,98,98,99,117,134

The mode will still be the same as the highest in frequency will still be 98

however the range will change

This is the difference between the highest and the lowest numbers

Before the addition of the two numbers, the range is 134-96 = 38

adding the two numbers, the range will become;

134-93 = 41
