a student recorded the quiz scores for the first semester on the line plot. if the outlier(s) were removed, what would be the mean score?

The mean score when the outlier removed is 8.

Step-by-step explanation:

The number of quiz scores were 15.

The scores are 3,6,7,7,7,7,8,8,8,8,8,9,9,10,10.

That is he scored 4 times 7, 5 times 8, 2 times 9 and 10.

The mean .

.

m= 7.67.

If outlier 3 is removed then remaining score are 6,7,7,7,7,8,8,8,8,8,9,9,10,10.

The number of quiz scores will be 14

The mean .

Here .

.

m= 8.

The mean score when the outlier removed is 8.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
