In a survey of 240 students in an elementary statistics class at the University of California-Davis (UCD), 31 said that they were left-handed and 209 said that they were right-handed. Assume that the students are representative of all students at the school. Does this provide evidence that the proportion of UCD students who are left-handed differs from the national proportion of 0.10? Carry out the five steps of the hypothesis test for this situation. (Use ? = 0.05.) Set up the null and alternative hypothesis. (Enter != for ≠ as needed.) H0: Ha: Compute the test statistics for this situation. (Round your answer to two decimal places.) z = Calculate the p-value for the test. (Round your answer to four decimal places.)
