Question

warm up 9/3
find the mean of each set of data to the nearest hundred

1. 12, 12, 12, 34, 16, 21, 11, 20, 15
2. 200, 175, 195, 250

Explanation:

Step1: Calculate sum of data in set 1

$12 + 12+12 + 34+16+21+11+20+15=153$

Step2: Divide by number of data points

$\frac{153}{9}=17$

Step3: Calculate sum of data in set 2

$200 + 175+195+250 = 820$

Step4: Divide by number of data points

$\frac{820}{4}=205$

Answer:

1. 17
2. 205
