Seventy-fivesuccesses were observed in a random sample ofn= 120

observations from a binomial population. You wish to show thatp> 0.5.

State the null and alternative hypothesis.

H₀:p< 0.5 versusH_a:p> 0.5

H₀:p= 0.5 versusH_a:p> 0.5

H₀:p0.5 versusH_a:p= 0.5

H₀:p= 0.5 versusH_a:p< 0.5

H₀:p= 0.5 versusH_a:p0.5

Calculate the appropriate test statistic. (Round your answer to two decimal places.)

z=

Provide an= 0.05 rejection region. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.)

z>z<

State your conclusion.
