Step-by-Step Solution
Class size = 22 - 17 = 5, half = 2.5, so classes are 14.5-19.5, 19.5-24.5, 24.5-29.5, 29.5-34.5, 34.5-39.5. Values >= 24.5 lie in the last three classes: 12 + 9 + 8 = 29.
Answer: D) 29
A continuous frequency distribution has class marks 17, 22, 27, 32, 37 and corresponding frequencies 3, 8, 12, 9, 8.
Using the class width from the class marks, how many observations have a value of 24.5 or more?
