The table shows the probabilities of certain prizes in a restaurant's contest where the first 100 customers are winners. How does the $100 gift card affect the measure of center of the data? A) it increases the mean value of the prizes B) it decreases the mean value of the prizes C) it increases the median value of the prizes D) it decreases the median value of the prizes

A) it increases the mean value of the prizes.

Step-by-step explanation:

The median is resistant to large outliers, so it does not change if there is an especially large or small value. So, we can eliminate choices C and D.

I am actually not sure whether the data in the table count $100 as a large prize or a small one, but I am assuming it is a large prize. So, an extremely large prize would increase the mean value of the prizes.

Hope this helps!

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
