Q1) What is critical T value for testing at the .01 level of significance?

Q2) Assume that the calculated test statistic is 2.88 (use this value even if you found another value in your calculations). Then what is the conclusion to the hypothesis test? (use critical t value from Q1)

\fWhat is the critical t-value for testing at the 0.01 level of significance? O 0.01 O 3.11 O 1.36 2.72 O 1.80 . Previous NextA researcher wants to determine the effect of an energy drink on people's productivity. 12 people volunteered to participate in the study. The participants were given two equally difficult tasks, one before having the energy drink and one after having the energy drink. The time that each person took to complete each task was recorded. The researcher wants to know whether task completion time after consuming the energy drink is less than that before consuming it. The results of the study are shown below
