Question
How would I find the z score and p value I have my work above
The director of student services at Oxnard College is interested in whether women are less likely to attend orientation than men before they begin their coursework. A random sample of freshmen at Oxnard College were asked what their gender is and whether they attended orientation. The results of the survey are shown below: + F3 What can be concluded at the a= 0.01 level of significance? For this study, we should use z-test for the difference between two population proportions a. The null and alternative hypotheses would be: F4 Ho: p1 p2 v (please enter a decimal and note that p1 and ul represent the proportion and mean for women and p2 and 2 represent the proportion and mean for men.) H₁: p1 b. The test statistic z c. The p-value = 4940 d. The p-value is va e. Based on this, we should fail to reject f. Thus, the final conclusion is that ... $ Data for Gender vs. Orientation Attendance C Yes 354 No 315 F5 Women Men 363 272 % F6 The results are statistically insignificant at a = 0.01, so there is statistically significant evidence to conclude that the population proportion of freshmen women at Oxnard College who attend orientation is the same as the population proportion of freshmen men at Oxnard CIL MLI9 p2 = -0.015 x (please show your answer to 3 decimal places.) x (Please show your answer to 4 decimal places.)
