- What is the Degrees of Freedom and What is the t-critical value at alpha .05?Find the t-values that form the boundaries of the critical region for a two-tailed test with alpha of .05 for the n = 15A researcher did a one-tailed one-sample t-test to test the hypothesis that babies prefer the color blue over the color red. He collected a sample of 26 babies and presented them with a red plastic star and a blue plastic start for 12 seconds. The researcher measured the amount of time each baby spent watching the blue star out of the 12 seconds. What is the critical t value, assuming the alpha level used was .05?
