The table shows the number satisfied in their work in a sample of working adults with a college education and in a sample of working adults without a college education. Assume that you plan to use a significance level of alpha=0.05 to test the claim that p1>p2. Find the critical value(s) for this hypothesis test. Do the data provide sufficient evidence that a greater proportion of those with a college education are satisfied in their work?
                                                    College Education      No college education     
Number in sample                                194                                  188                       
number satisfied in their work           74                                    70
The answer that I got was z=1.645;no.
A)z=1.645;no
B)z=-1.645;yes
C)z=1,96;yes
D)z=+-1.96;no

I used the same one as before and got something completely different

Probably not, how did you get 1.645? I might be wrong, but will look into it in 3 hours -- currently out

But please do update me on your method

alpha = 0.05

0.05 / 2 = 0.025, which has a z = ± 1.96

Choose D
- Master of Science in Biology
- Bachelor of Science (Biology)
- Bachelor of Education

Upwards Arrow That makes no sense, duddy.

According to this document I uploaded, the answer is (A)

But I'm not sure how it's derived.
