Frequency Distribution Problems

The following data set shows the minutes spent on internet by 50 internet users. Use the class width from the previous question to find the lower class limits if the first lower class limit is the minimum value of the data set.

• 7, 7, 11, 17, 19, 20, ...

• 6.5, 18.5, 30.5, 42.5, 54.5, 66.5, 78.5

• 12.5, 24.5, 36.5, 48.5, 60.5, 72.5

• 7, 19, 31, 43, 55, 67, 79
