End State the null and alternate hypotheses. Ho: Myers-Briggs type and area of study are independent. H,: Myers-Briggs type O Ho: Myers-Briggs type and area of study are not independent. H, : Myers-Briggs type and area of study are independent. Home O Ho: Myers-Briggs type and area of study are independent. H1: Myers-Briggs type and area of study are independent. O Ho: Myers-Briggs type and independent. H, : Myers-Briggs type and area of stu (b) Find the value of the chi-square statistic for the sample. (Round the expected frequenc cimal places. Round the test statistic to three Prison decimal places.) Are all the expected frequencies greater than 5? Yes NO What sampling distribution will you use? O binomial O' Student's t O chi-square O normal O uniform What are the degrees of freedom? (c) Find or estimate the P-value of the sample test statistic. (Round your answer to three decimal places.) O p-value > 0.100 O 0.050 a, we fall to reject the null hypothesis. Since the P-value the null hypothesis. 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 At the 5% level of signif ndependent
