Census data for a certain county were used to construct the following frequency distribution for commute time (in minutes) of working adults. Commute Time Relative Frequency 0 to <5 0.0544 5 to <10 0.1800 10 to <15 0.1929 15 to <20 0.1513 20 to <25 0.1355 25 to <30 0.0574 30 to <35 0.0999 35 to <40 0.0218 40 to <45 0.0218 45 to <60 0.0386 60 to <90 0.0227 90 to <120 0.0237 (a) Notice that not all intervals in the frequency distribution are equal in width. Why do you think that unequal width intervals were used?

Identify the lower class​ limits, upper class​ limits, class​ width, class​ midpoints, and class boundaries for the given frequency distribution. Also identify the number of individuals included in the summary.

Use the Histogram tool to develop a frequency distribution and histogram for the number of months as a customer of the bank in the data below. Compute the relative and cumulative relative frequencies and use a line chart to construct an ogive.   Complete the frequency distribution for the months as a​ customer, and compute the relative and cumulative relative frequencies. ​(Type integers or decimals rounded to three decimal places as​ needed.)
