Title: Critical values question Post by: Biala on Jul 30, 2019 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 Title: Re: Critical values question Post by: bio_man on Jul 30, 2019 Can you tell me what formula you use?
I used the same one as before and got something completely different Title: Re: Critical values question Post by: Biala on Jul 30, 2019 I think maybe I did something wrong.
Title: Re: Critical values question Post by: bio_man on Jul 30, 2019 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 Title: Re: Critical values question Post by: duddy on Jul 30, 2019 alpha = 0.05
0.05 / 2 = 0.025, which has a z = ± 1.96 Choose D Title: Re: Critical values question Post by: bio_man on Jul 30, 2019 ^^ That makes no sense, duddy.
According to this document I uploaded, the answer is (A) https://biology-forums.com/index.php?action=downloads;sa=view;down=12892 But I'm not sure how it's derived. |
