Question

A data set of the age of a sample 275 gallopicus tortillas has a minimum value of one year and a maximum value of 95 years suppose we want to group these data into 5 classes of equal width assuming we take the lower limit at the 1st class as 1 year determined the class limit boundaries and mid point of the group quantitative data table

Answer 1

`\text{class width=}(95-1)/(5)=(94)/(5)=18.8\approx19`

Therefore,

`\text{class mid point=}\frac{lower\text{ class limit + upper class limit}}{2}`
