The following data show the price of silver and the price of tin over a recent 9-year period. Find the range, variance, and standard deviation. Which data set is more variable? I was able to find the range, variance, and standard deviation, but I’m lost by the last question. More variable? How do I go about answering that?

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
