2- two population proportions

image text in transcribed
The director of student services at Oxnard College is interested in whether women are just as likely to attend orientation as 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: Data for Gender vs. Orientation Attendance Women |Men Yes 305 385 No 305 294 What can be concluded at the a = 0.10 level of significance? For this study, we should use z-test for a population proportion VX a. The null and alternative hypotheses would be: Ho: P1 VVE Y p2 (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 V V # vv p2 (Please enter a decimal) b. The test statistic z v V = 5.800 x (please show your answer to 3 decimal places.) c. The p-value = 0.0160 (Please show your answer to 4 decimal places.) d. The p-value is > v x a e. Based on this, we should reject vv the null hypothesis. f. Thus, the final conclusion is that ... The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude that the population proportion of freshmen women at Oxnard College who attend orientation is different from the population proportion of freshmen men at Oxnard College who attend orientation
