Question
Consider the probability distribution of X, where X is the number of job applications completed by a college senior through the school’s career center.
We collect a random sample of 1000 college seniors who complete job applications through the career center. Based on the probability distribution, which result would be surprising?
14 seniors completed 1 job application through the career centers.
15 seniors completed 2 job applications through the career center.
130 seniors completed 3 job applications through the career center.
X 0 1 2 3 4 5 6 7 P(X) 0.002 0.011 0.115 0.123 0.144 0.189 0.238 0.178Explanation / Answer
Based on the probability distribution,
Number of persons completed 1 job application is 1000* 0.011 = 11 ( close to 14)
Number of persons completed 2 job application is 1000* 0.115 = 115
Number of persons completed 3 job application is 1000 * 0.123 = 123 ( close to 130)
We can see that other than number of persons completed 2 job application are close to the result
So result of number of persons completed 2 job application is suprising
