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

For a grouped frequency distribution having eight classes, the upper class boundaries of the lowest and the highest classes are 10 and 66 respectively. What is the lower class boundary of the highest class?

From the given frequency table, find the class mark of the class interval having the highest frequency.
