Answer 1

To calculate the mean without the outlier, we first need to identify any outliers in Eli's scores: 84, 95, 97, 98, 98, and 100.

Based on these scores, 84 appears to be an outlier as it is significantly lower than the others.

Now, we will calculate the mean of the remaining scores: 95, 97, 98, 98, and 100.

1. First, add these scores together:
\[
95 + 97 + 98 + 98 + 100 = 488
\]

2. Next, count how many scores we have:
There are 5 scores.

3. Now, divide the total sum by the number of scores to find the mean:
\[
\text{Mean} = \frac{488}{5} = 97.6
\]

So, the mean without the outlier is **97.6**.
