10 The length of time taken by 80 drivers to complete a particular journey is summarised in the table below. (a) Using a scale of 2 cm to represent 10 minutes, draw a horizontal axis for times from 60 minutes to 130 minutes. Choose a suitable scale for the vertical axis and draw a histogram to represent this information. (b) In which of the intervals does the median time lie? (c) Calculate an estimate of the mean time taken to complete the journey. (d) One driver is chosen at random. Calculate the probability that this driver took 95 minutes or less for the journey. (e) Two of the 80 drivers are chosen at random. (i) Calculate the probability that both took more than 100 minutes for the journey. (ii) Calculate the probability that one took 80 minutes or less and the other took more than 110 minutes.
