Are all the expected frequencies greater than 5? Yes O No What sampling distribution will you use? O chi-square O Student's t O binomial O uniform O normal What are the degrees of freedom? (c) Find or estimate the P-value of the sample test statistic. O p-value > 0.100 O 0.050 or, we fail to reject the null hypothesis. Since the P-value > ox, we reject the null hypothesis. O Since the P-value s or, we reject the null hypothesis. O Since the P-value s or, we fail to reject the null hypothesis. (e) Interpret your conclusion in the context of the application.
