A hypothesis test was conducted to test whether has been an increase in the proportion of students that attend college right aft
er high school. The resulting p-value from that test was .000548. Given an alpha level of .05, which of the following is TRUE? A. There is no evidence to show an increase in the proportion of students attending college because the p-value is less than the alpha level, therefore we will fail to reject the null hypothesis.
B. There is evidence to show an increase in the proportion of students attending college because the p-value is less than the alpha level, therefore we will reject the null hypothesis.
C. There is evidence to show an increase in the proportion of students attending college because the p-value is less than the alpha level, therefore we will fail to reject the hypothesis.
D. There is no evidence to show an increase in the proportion of students attending college because the p-value is less than the alpha level, therefore we will reject the null hypothesis.
D. There is no evidence to show an increase in the proportion of students attending college because the p-value is less than the alpha level, therefore we will reject the null hypothesis.
Step-by-step explanation:
Assuming a significance level of α=0.05, since 0.000548<0.05, we reject the null hypothesis and conclude that there is no evidence to show an increase in the proportion of students attending college. So option D is correct.
As I increases by 18, y decreases by 12. From the last value in the table, I needs to increase by 2·18 for it to become zero. Hence the y-intercept will be 2·12 less than the last value in the table:
