Consider testing the hypothesis 0 : = 0.2 and : > 0.2

Which sample proportion is most likely to show statistical significance? (if we assume the sample size is the same in every case.):

= 0

= 0.25

= 0.4

= 0.7

Which sample proportion is least likely to show statistical significance? (if we assume the sample size is the same in every case.):

= 0.1

= 0.25

= 0.4
