How do I find the number of classes in a frequency histogram.
6. Fill in the missing values in the following table of relative frequency, labelled A- J. Show how you calculate each value, and put your final answer for each value in the table below (e.g., replace "A" with your found value). The method you use can be different from mine, but you must show how you arrive at each value. Hint: go in order. Find A, then B, etc. Tutorial video 3 should be very helpful here. Class Frequency Relative frequency Cumulative relative frequency 1 to 5 300 0.15 0.15 6 to 10 B A 0.20 11 to 15 500 C D 16 to 20 F 0.45 E 21 to 25 H G 0.98 26 to 30 J I 1.00

Finish times (to the nearest hour) for 10 dogsled teams are shown below. Make a frequency table showing class limits, class boundaries, midpoints, frequency, relative frequencies, and cumulative frequencies. Use three classes. (Round your answer for relative frequency to the nearest hundredth and for midpoint to the nearest tenth.) 308 262 310 268 299 249 257 286 239 278
In the frequency distribution below, the first column (class limits) gives the age ranges (in years) of people who participate in a survey. The second column gives the frequency for each age range. a. Determine the class width. If needed, you can use the space below the table. b. Complete the rest of the frequency distribution. For the relative frequency column, round your answers to 2 decimal places. Class Limits Frequency Class Boundaries Class Midpoints Relative Frequency Cumulative Frequency 18-26 16 27-35 24 36-44 38 45-53 34 54-62 26 63-71 12 Total 150
