A university is offering a special job education program for students. The program is in 3 steps. Finishing each step requires 3 hours of lecture. The university has to decide whether it is going to promote this program. Five students who graduated last year were selected randomly and interviewed to provide the following data:

StudentSteps Finished (x)Job Offers (y)
11 4
22 6
31 3
40 1
53 5

To see the effectiveness of the job education program, the university conducted a simple least squares analysis with these data which yielded:

Offers = 1.81 + 1.42Steps.

Which of the following statements best interprets this result?
- On average, the students who join the program are expected to have 1.42 more job offers than the non-participants regardless of the steps they finished.
- On average, the students who join the program are expected to have 1.81 job offers.

When distilling cyclohexanol to get cyclohexene, why do you shake saturated sodium chloride solution with the crude alkene? Does this help to remove impurities in some way? I can't find the answer anywhere! Also, why is anhydrous calcium chloride added to the cyclohexene? Is it to remove excess water from the alkene? Any help would be much appreciated!!

In my quantum class of 40 students, 4 were women. I heard the numbers get worse as educational status (and age) increases.
