Assumptions:  a) Simple Random Sample         b) n(p)(1-p) ≥ 10

Step 1: Set up null and alternative hypotheses.

H0: p =

H1: p >



Step 2: Determine level of significance of hypothesis test.

α =     (Note: α = level of significance of hypothesis test   = probability of making Type I error.)

Step 3: Calculate Test Statistic.

p̂ = sample proportion =          (Note: p̂ = x/n)

n = sample size =

Calculate Test Statistic z:
       blank
       (Note: Value of p comes from Step 1)






Step 4: Determine P-value

Using the test statistic in Step 3 as a z-score, we will find the right-tailed area corresponding to this z-score.
