Answer:
Explanation:
(a) Calculate the approximate probability that between 35 and 70 tickets are given out on a particular day.
(using continuity correction)
= 0.9981 - 0.0143 (using standard normal tables)
= 0.9839
b) Consider is the random variable that represents the number of parking tickets issued in certain city in a 5-day week
The mean number of parking ticket issued in a particular city on 5-day week is
Therefore, the required probability is
= 0.9463 - 0.0537 (using standard normal tables)
= 0.8926
c)<em> see the attached file </em>
<em>image 1 (the approximate probability of part a )</em>
<em>image 2 (the approximate probability of part b )</em>
From the two graph observed that the probability obtained using software is approximately same as calculated by manually
