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 347 409 Yes 355 No 324 What can be concluded at the a = 0.05 level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer ✓ Select an answer ✓ Select an answer (please enter a decimal and note that p1 and μl represent the proportion and mean for women and p2 and µ2 represent the proportion and mean for men.) H₁: Select an answer Select an answer ✓ Select an answer ✓ (Please enter a decimal) b. The test statistic ? ✓ = c. The p-value = d. The p-value is ? ✓ α e. Based on this, we should [Select an answer the null hypothesis. f. Thus, the final conclusion that (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) The results are statistically significant at a = 0.05, 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. The results are statistically insignificant at a = 0.05, so there is insufficient 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. The results are statistically insignificant at a = 0.05, 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 College who attend orientation. The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the proportion of the 679 freshmen women who attended orientation is different from the proportion of the 756 freshmen men who attended orientation.
