Question

This is from a study titled, “Increasing Community College Graduation Rates with a Proven Model: Results from the Accelerated Study in Associate Programs (ASAP) Ohio Demonstration.” Ohio community college students were randomly assigned to either the ASAP program or the control group. Students in the ASAP program received increased financial assistance and intensive counseling. Students in the control group received less financial assistance and less counseling. Even after only one semester, the program had a statistically significant result. 0.3% of ASAP program participants earned a college degree in semester 1, while 0.0% of the control group earned a degree in semester 1. The result’s p value is .095. The result is statistically significant at the _______ confidence level. 20. What number should go in the blank? In other words, at what confidence level is this result statistically significant? Write one or two complete sentences interpreting the result. What does it mean that the result was statistically significant?

Answer 1

Here we want to test that financial assistance received in ASAP program is higher than the financial assistance in the control group.

Here the result's p value is 0.095 . We know a test is statistically significant if the p value is less than the level of significance of the test.

So here level of significance must be 0.1 . Because 0.095 is less than 0.1

So the level of significance of the test is 0.1

Which is same as the confidence level of 90%

So the result is statistically significant at 90% confidence level.

Statistically significant means the two variables that we are testing are not equal. Here the test is statistically significant means our claim is supported by tha data. Which is the financial assistance received in ASAP program is higher than the financial assistance in the control group.
