## Welch Two Sample t-test
##
## data: completed$math_score and none$math_score
## t = 5.787, df = 770.08, p-value = 1.043e-08
## alternative hypothesis: true difference in means is not equal to 0
## 95 percent confidence interval:
## 3.712041 7.523257
## sample estimates:
## mean of x mean of y
## 69.69553 64.07788
to provide evidence on whether the prep course was effective was performed at 0.05 level of significance
the null was rejected when it gave a p-value equal to 1.043e-0b. the mean for the test proved that the students who did not take the test is less than the students who completed the test prep. there is enough proof to show that the test prep works
