Do iii and iv. b) Drivers were surveyed to determine their rest time taken at the Rest & Recreation (R&R)area when they travelled back to their hometowns, during the Hari Raya holidays. Arandom sample of 50 drivers was selected, and the time taken by each driver to stop atthe R&R were summarized as follows:Time taken to stop at the R&R (in minutes) Number of drivers480 and less than 1010 and less than 2020 and less than 3030 and less than 4040 and less than 501312750 and less than 606i) Construct a 'less than' ogive for the above dataii) From the ogive obtained in (i), estimate the value of X if 50% of the drivers tookmore than X minutes to stop at the R&R, and another 50% of the drivers took lessthan X minutes.iii) Find the mean and the standard deviation of the time taken by each driver to stop atthe R&R.iv) Compute the Pearson's coefficient of skewness and describe the shape of thedistribution.

Mean of the time taken by each driver to stop at the R&R is 30.6 minutes. Standard deviation…
