(See Figure 8-3 on page 391.) C. Using a significance level of α = 0.05, should we reject Ho or should we fail to reject Ho? XE 20. The test statistic of z 1.94 is obtained when testing the claim that p 3/8. URE Finding P-Values CAUTION Don't confuse a P-value with the parameter p or the statistic p. Know the following notation: P-value = probability of a test statistic at least as extreme as the one obtained p = population proportion sample proportion PIC.COLLAGE
