Find test statistic and p-value and make conclusion for MEAN: x=35, n=200, Ho: p=25%, H1: p<25%, confidence level=0.05 Then find test statistic and p-value and make conclusion for PROPORTION: x̄=37, s=10.2, n=30, Ho: μ=32, H1: μ≠32, confidence level=0.01 Now find test statistic and p-value and make conclusion for TWO PROPORTIONS: x1 = 6, n1 = 315, x2 = 80, n2 = 320, Ho: p1 = p2, HA: p1 < p2, α = 0.1

In order to test HO: p = 0.59 versus H1: p < 0.59, use n = 150 and x = 78 as your sample proportion. Using your TI 83/84 calculator device, find the P-value with the appropriate Hypothesis Test Use a critical level α = 0.01 and decide to Accept or Reject HO with the valid reason for the decision. A. My P-value greater than α Alpha, so I Reject Null Hypothesis B. My P-value greater than α Alpha, so...
