P value rules
WebA p-value is a probability, a number between 0 and 1, calculated after running a statistical test on data. A small p-value (< 0.05 in general) means that the observed results are so … WebThe test statistic is, therefore: Z = p ^ − p 0 p 0 ( 1 − p 0) n = 0.853 − 0.90 0.90 ( 0.10) 150 = − 1.92. And, the rejection region is: Z P lesson 9.3 α = 0.05 -1.645 0 0.90. Since the test statistic Z = −1.92 < −1.645, we reject the null hypothesis. There is sufficient evidence at the α = 0.05 level to conclude that the rate has ...
