1. For each restaurant's service times, do the following.

1. Create a frequency distribution with the given classes. Include the frequency, class boundaries, relative frequency, and cumulative frequency of each class.

Class
$30$$49$
$50$$69$
$70$$89$
$90$$109$
$110$$129$
2. Use the frequency distribution to construct a histogram of the data.

2. Based on the graphical descriptions of the data you created in part 1, which fast-food restaurant do you believe consistently has the shortest service times? Explain why.
