Hypotheses:H₀: p = .25Hₐ: p ≠ .25:ConditionsNOT stated-- proceed with caution!662.2 ≥ 10and 3010(1 - .22) =2347.8 ≥ 1030100 < all adults(reasonable to assume)Test statistic:Conduct the two-tailed test to calculate the area corresponding to the positive and negative z-score.

p = .0001441Conclusion:Since

p = .0001441 < α = .05, wereject the null hypothesis. Thereis convincing statistical evidencethat thetrue proportionof adults that use the internet isnot equal to .25.
