 (a). What is the probability of selecting a graduate whose major is management and does have job offer?

 

(P) Management major with job offer = 35/180=

 

(b). If a graduate selected is supply chain major, what is the probability that the graduate has no offer?

 

(P) Supply chain majors with no job offer = 15/40 =

 

(c). What is the probability of selecting a finance major graduate?

 

(P) Selecting finance major = 35/180 =

 

(d). What is the probability that you select a graduate who either majors in accounting or has job offer?

 

(P) Accounting majors or job offers = (50/180)+(100/180) – (15/180)=

 

2. The following table lists the total number of alumni by the number of job offers they have gotten around graduation (10 points, 5 points each, Review PPT page 10).

  1. What is the probability that a graduate has 1 or fewer job offer?

 

(P) Graduates with 1 or less job offers = 90/200 =

 

  1. What is the probability that a graduate has 3 or more job offers?

 

(P) Graduates with 3 or more job offers = 60/200 =

 

3. The alumni responded that it took about 5 to 65 days to get the first offer. Supposed the time needed to get the first offer is a uniform probability distribution. Please calculate (20 points, 10 points each, Review PPT page 13-15). 

 

  1. The probability of taking the alumni to get their first offer for fewer than 25 days.

 

P (5<x<25) = (1/65-5)(25-5)=

 

  1. The probability of taking the alumni to get their first offer between 15-50 days.

 

P (15 < x <50) = (1/65-5)(50-15) = 0.0167(35)=

 

4. The dean has observed for several years and found that the probability distribution of the salary of the alumni’s first job after graduation is normal, with a mean of $56k per year and a standard deviation of $4k (30 points, 10 points each, Review PPT page 16-25):

 

  1. What’s the probability that the alumni get a salary of $52k or more in their first jobs?

 

Z= x-mean/st dev= 52-56/ 4 = -4/4 = -1

Z value 1 = P(x) 0.3413

 

P(annual salary > $52k) = .500 +0.3413=

 

 

  1. What’s the chance that the alumni get a salary between $40k and $60k?

 

Z = 60-56/4 = 1

Z= 1 = P(x) = 0.3413

P ($40k < annual salary < $60k) =

 

 

  1. What is the salary range that 95% of the alumni should be belonged to?

 

Empirical rule formula +/-2 deviations (4k) from mean (56k)

 

Salary range should be from

 

 

 

 

 

5. Suppose the distribution of alumni salary has a mean of $56k per year and a standard deviation of $4k. The research office collected salary information from 100 business alumni. Its collected data show that the mean salary of their first job is $58k per year (20 points, 10 points each, Review PPT page 27-29.

 

  1. What is the sample size and standard error of the data collected?

 

 

  1. What is the probability that the sampled alumni have a mean salary of $58k or more?
