Please complete cumulative Frequency for 5 & 6 that were cutoff from image thanks!

You are given the data below. Complete parts a through d. 12 11 13 11 10 12 14 13 15 8 6 5 13 6 15 9 5 11 7 12 10 5 13 14 10 11 13 15 14 10 13 5 11 7 15 11 5 15 8 15 5 5 10 6 12 10 a. Construct a grouped data relative frequency distribution of the data. Use the 2" 2 n guideline to determine the number of classes to use. (Use the minimum class width, rounded up to the nearest integer. Start the first class at the minimum value) (Type integers or decimals rounded to three decimal places as needed.) Class Data Values Relative Frequency Q UI A W N - b. Construct a cumulative frequency distribution of the data. Cumulative Class Frequency W N
