Question
The frequency distribution table of heights (in centimeters) of a group of students with a class width of 6 are as follows: 150, 152, 154, 156, 158, 160, 162, 164, 166, 168. What is the lower boundary of the class interval 156-161?Group of answer choices161.5160155.5156.5
Solution
The lower boundary of the class interval 156-161 is 155.5. This is because the class width is 6, so you subtract half of this (3) from the lower limit of the class interval (156) to get the lower boundary.
