A breakdown of the number of rhinos of each species is reported in the accompanying table. a. Construct a relative frequency table for the data. b. Display the frequencies in a bar graph. c. Display the frequencies in a pie chart. d. What proportion of the 25280 rhinos are White rhinos? Black? 6. You are working for the transport manager of a "call centre" which hires cars for the staff. You are interested in the weekly distances covered by these cars. Kilometers recorded for a sample of hired cars during a given week yielded the following data: a) Find average distances by suitable method. b) Draw an ogive curve and find the median, Q2, P50, and D5. c) Find graphically the number of cars that covered less than 165km in the week
