Question

When the outlier(s) are removed, how does the mean change? dot plot with 1 dot over 15, 1 dot over 23, 1 dot over 24, 1 dot over 25, 1 dot over 26, 1 dot over 27, and 1 dot over 35
The mean doesn't change.
The mean increases by 2.
The mean decreases by 2.
There are no outliers.

Answer 1

Answer:

So the answer is A-The mean doesn't change

Step-by-step explanation:

With the outliers the mean is 25, how?

well if we put down the numbers 15,23,24,25,26,27,35 and add them together  15+23+24+25+26+27+35 we get 175 now we have to divide by how many numbers are there 175/7=25. That is the mean WITH the outliers.

Now, WITHOUT the outliers. The outliers are 15 and 35. We know this because, there is a huge gap between 15 and 23, and 27 and 35. We basically do the same thing but without the outliers. 23+24+25+26+27=125 we divide by how many numbers are there 125/5 then we get 25.

Answer 2

Hey love! <3

Answer:

The correct answer is A. The mean doesn't change

Step-by-step explanation:

Since this is a dot plot, first we have to count up the total x-axis amount from the dot plots, then divide it by the numeral amounts (y-axis), then repeat this after removing the outlier from the dot plot.

Thus, the mean remaining the same.
