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.
Accepted Solution
A:
Answer:Option bStep-by-step explanation:Given that the probability distribution of X, where X is the number of job applications completed by a college senior through the school’s career center. Expected observed Diff
x p(x) p(x)*1000
0 0.002 2
1 0.011 11 14 -3
2 0.115 115 15 100
3 0.123 123 130 -7
4 0.144 144
5 0.189 189
6 0.238 238
7 0.178 178
1 1000 We find that there is a large difference in 2 job applicationHence option b is right.
