Again suppose that the local council uses a potentially different Poisson distribution to model the number of people arriving at a specic point on a bike path during the busiest time of the day. Let X denote the number of people arriving per hour and now assume that X N POIS(49). Suppose you observe the specic point on the bike path during the busiest time of the day for one hour and count the number of people arriving. This time suppose we wish to calculate the probability that less than or equal to 26 people arrive during the hour. This time] the Normal distribution will be used to approximate the required probability. The appropriate code would be: pnorm(a, b , c) where a, b and c need to be replaced with appropriate numbers. Answer the following, rounding to three decimal places where relevant. a. The number in position a should be: {7 mark) b. The number in position b should be: {7 mark) c. The number in position c should be: (7 mark)
