i need help with part 3. For part 3 to be answered the information has to be gotten from 1 and 2. I gave the answers to part 1.

ArnecanMade Cars 1c Below is the relative frequency table for American made cars. Each relative frequent}.r is found by taking the actual frequency and. dividing it by 513.

(b) Create a histogram from the table. (c) Create a relative frequency table from the frequency table. ((1) Create a cumulative and relativecumulative frequency table. (e) Estimate the mean MPG for the Americanmade cars included in this set. 3. Comparing Distributions: Use your answers from the previous two problems to answer the following questions regarding the difference in distributions for MPG between cars made in America and cars made in Japan. (a) Do the distributions appear to be normal, skewed, uniform, or multi-modal? (b) Which country appears to make the most fuel efficient cars? (c) Which representation (frequency distribution, histogram, relative frequency distribution, cumu- lative frequency distribution, or relative-cumulative frequency) best allows you to compare the fuel-efficiency of the American-made and Japanese-made cars and why?2.
