(a) What is the level of significance? State the null and alternate hypotheses. O Ho: Myers-Briggs preference and profession are not independent H: Myers-Briggs preference and profession are independent. O Ho: Myers-Briggs preference and profession are not independent H1: Myers-Briggs preference and profession are not independent. O Ho: Myers-Briggs preference and profession are independent H : Myers-Briggs preference and profession are not independent. O Ho: Myers-Briggs preference and profession are independent H : Myers-Briggs preference and profession are independent. b) Find the value of the chi-square statistic for the sample. (Round the expected frequencies to at least three decimal places. Round the test statistic to three decimal places.) Are all the expected frequencies greater than 5? O Yes O No What sampling distribution will you use? O uniform O binomial O Student's t O normal O chi-square 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 a, we fail to reject the null hypothesis. O Since the P-value > a, we reject the null hypothesis. O Since the P-value s a, we reject the null hypothesis. O Since the P-value s a, we fail to reject the null hypothesis. (e) Interpret your conclusion in the context of the application. O At the 5% level of significance, there is insufficient evidence to conclude that Myers-Briggs preference and the profession are not independent.
