Consider testing the hypothesis null: p= 0.4and alternative :p<0.4

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

p-hat= 0.1 p-hat = 0.25 p-hat = 0.5 p-hat = 0.7

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

p-hat= 0.1 p-hat = 0.25 p-hat = 0.5 p-hat = 0.7
