Answer:
Frequency = 7
Explanation:
In the class 60 - 65:
The lower class limit = 60
The upper class limit = 65
In the given data set, to get the frequency of data in the class interval [60, 65) without including the upper class limit, we will have to list the numbers that fall within this range 60 to 65 without including 65 itself
62.23, 60.65, 62.68, 62.09, 63.45, 60, 60.89
There are 7 values in the interval [60, 65)
Frequency = 7
