27. You are developing a new way polygraph machine to sell to private investigators. The most popular machine currently used has an accuracy rate of 75%. You think that your newly developed machine will be more accurate than the current machine. You measured the accuracy rates of detecting lies in 10 subjects. The accuracy (in percentages) were 79, 77, 78, 81, 82, 76, 79, 83, 75, 80. What conclusion would you draw following a t test for a single sample using a .05 significance level? Use the five steps of hypothesis testing. Note that I gave you scores in the X column instead of Sum of Squares (SS). You will have to calculate this yourself.
