In a survey of 240 students in an elementary statistics class at the University of California-Davis (UCD), 19 said that they were left-handed and 221 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.)
