MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER In a survey of 240 students in an elementary statistics class at the University of California-Davis (UCD), 17 said that they were left-handed and 223 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 $\alpha = 0.05$.) USE SALT Set up the null and alternative hypothesis. (Enter != for $\neq$ as needed.) $H_0$: $H_a$: 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.) $p$-value = this situation.
