y=10,22,16
Expert Solution
Step 1
Given : Score for the Statistics Quiz (X), and the score for the Math Quiz (Y) is provided .
- The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:
Statistics Quiz (X) :
Sum of terms = 3 + 7 + 5 = 15
Number of terms = 3
=
Mean = 5
Math Quiz (Y) :
Sum of terms = 10 + 22 +16 = 48
Number of terms = 3
=
Mean = 16
