The following data are the time taken for runners to finish a 5-kilometer run in a running event. Time (minutes) 10 - 19 20-29 30 - 39 40 - 49 50-59 60 - 69 Number of runners 6 18 25 32 22 10 a) Calculate the mean, median and standard deviation for the above data. (8 marks) b) Determine the shape of distribution for the data by using Pearson's coefficient of skewness. (2 marks)

The Following Data Are The Time Taken For Runners To Finish A 5 Kilometer (37.88 KiB) Viewed 342 times

b) Pearson's coefficients correlation = 3* ( mean - median)/ standard deviations

= 3*(41.2257-41.8438)/13.3926 = −0.13845705837 answer
