"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.
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 0.178
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? "
a. 14 seniors completed 1 job application through the career centers.
b. 15 seniors completed 2 job applications through the career center.
c. 130 seniors completed 3 job applications through the career center.

We find that there is a large difference in 2 job application
Hence option b is right.
