The results are statistically significant at αα = 0.05, so there is sufficient evidence to conclude that the proportion of the 605 freshmen women who attended orientation is less than the proportion of the 785 freshmen men who attended orientation.

Data for Gender vs. Orientation Attendance

	Women	Men
Yes	374	522
No	231	263

What can be concluded at the αα = 0.05 level of significance?

For this study, we should use? Select an answer t-test for a population mean z-test for the difference between two population proportions? z-test for a population proportion? t-test for the difference between two dependent population means? t-test for the difference between two independent population means?

The null and alternative hypotheses would be:

μ1 Select an answer > = ≠ < Select an answer p2

μ2 (please enter a decimal)

H1:H1: Select an answer μ1

p1 Select an answer < = ≠ > Select an answer p2

μ2 (Please enter a decimal)

2. The test statistic ? z

t =

______

(please show your answer to 3 decimal places.)

The p-value = ______ (Please show your answer to 4 decimal places.)

The p-value is ? > or ≤ α

3. Based on this, we should Select an answer reject? accept? fail to reject? the null hypothesis.

Thus, the final conclusion is that ...

The results are statistically insignificant at αα = 0.05, so there is insufficient evidence to conclude that the population proportion of freshmen women at Oxnard College who attend orientation is less than the population proportion of freshmen men at Oxnard College who attend orientation.
