Question
Identify the class width, class midpoints, and class boundaries for the given frequency distribution Ful data set Height (inches) 85.0.88.9 89.0-92.9 93.0-96.9 97.0-100.9 01.0-104.9 Height (inches) Frqency Fr Frequency 0.689 69.0-72.9 73.0.76.9 77.0.80.9 81.0-849 25 What is the class width? What are the class midpoints? 66.95.70.95. 7495, 78.95. 82.95.86.95,90.95,9495,98.95,102.95 (Use ascending order.Round to two decimal places as needed.) What are the class boundaries? (Use asoending order. Round to two decimal places as needed.)Explanation / Answer
The class width is 65 to 68.9=4
Class mid points
(68.9+65)/2=66.95 Similarly 70.95,74.95,82.95,86.95,90.95,94.95,98.95,102.95
Class boundaries can be found by adding upper limit of first class added to lower limit of next class divided by 2
(68.9+69)/2=68.95
68.95 72.95 76.95 80.95 84.95 88.95 92.95 96.95 100.95 52.45
