Solution

## To make our job easy at first we can arrange the data in ascending order. {1, 2, 3, 4, 4, 7, 9, 10, 12, 14, 14, 17}. We know that frequency gives the number of times a particular entry occurs. In this data set: Greater than or equal to 0 and less than 5, we have 5 observations. Greater than or equal to 5 and less than 10, we have 2 observations. Greater than or equal to 10 and less than 15, we have 4 observations. Greater than or equal to 15 and less than 20, we have 1 observation.
