Answer:
A. The mean will increase.
Step-by-step explanation:
The mean is the average of the numbers. You just add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
84 + 75 + 76 + 80 + 48 + 75 = 438
438 / 6 = 73
mean = 73
The outlier is 48, so when you remove it, there will now be only five numbers in the set, and the mean will increase in size.
84 + 75 + 76 + 80 + 75 = 390
390 / 5 = 78
NEW mean (without the outlier) : 78
