Question 1

A pie chart shows a $500K budget: Operations=40%, Marketing=25%, R&D=20%, Admin=15%. How much more is spent on Operations than Admin?

Accepted Answer

$125,000

Answer

Operations = $200K, Admin = $75K; difference = $200K − $75K = $125,000.

Question 2

A dataset of 10 values has a mean of 50 and a standard deviation of 5. A new data point of 75 is added. What effect does this likely have on the standard deviation?

Accepted Answer

It increases

Answer

Adding an outlier far from the mean increases spread, raising the standard deviation.
