Show answer & explanation
Correct answer: C
Complete Solution
To determine the new average, we apply the property of averages regarding arithmetic operations:
Understand the Property: If every number in a data set is increased by a constant value (k), the average of that data set will also increase by that same constant value (k).
Identify the variables:
Original Average = 32
Increase applied to each number (k) = 3
Calculate the New Average:
New Average = Original Average + k
New Average = 32 + 3 = 35
