Construct a frequency table and display it as a histogram using a class width of 10 starting at 0 on your own paper and answer the following questions. Where you enter your answers into the "Assignment 1 and Submission".[Recall:LCB is included in the class interval whereas UCB is not included.]Your first class should be [0, 10).

a)What is the class midpoint for the class interval [40, 50)?

b)What is the class frequency for the class interval [10, 20)?

c)What is the class frequency for the class interval [20, 30)?

d)What is the class relative frequency for the class interval [80, 90)?

e)What is the proportion of fundraising expenditures less than 10?

f)What is the proportion of fundraising expenditures greater and equal 40?

g)What is the proportion of fundraising expenditures between 10 and 60? (Note: including 10 and 60)
