Answer 1

To find the mean without the outlier, we need to first identify the outlier. In this case, the outlier is the score of 63.

So, we will calculate the mean of the remaining scores: 82, 96, 100, 91, 88, 82.

Adding these scores together we get: 82 + 96 + 100 + 91 + 88 + 82 = 539

Now, to find the mean, we divide the total by the number of scores: 539 / 6 = 89.8

Rounded to the nearest tenth, the mean without the outlier is 89.8.

Therefore, the answer is 89.8.

Answer 3

Of course! Here is a step-by-step breakdown of how I calculated the mean without the outlier:

1. List the test scores: 82, 96, 100, 63, 91, 88, 82
2. Identify the outlier: 63
3. Remove the outlier from the list of scores: 82, 96, 100, 91, 88, 82
4. Calculate the sum of the remaining scores: 82 + 96 + 100 + 91 + 88 + 82 = 539
5. Count the number of remaining scores: 6
6. Find the mean by dividing the sum of the remaining scores by the number of scores: 539 / 6 = 89.8333 (unrounded)
7. Round the mean to the nearest tenth: 89.8

Therefore, the mean without the outlier is 89.8. Let me know if you need further clarification or have any other questions!
