Psychologist wants to determine if there is a linear relationship between the number of hours a person goes without sleep and the number of mistakes he/she makes on a simple test. The following data is recorded. Hours without sleep 32 38 48 24 46 35 30 34 42 Number of Mistakes 6 8 13 5 7 6 5 8 12 Hours without sleep=x, Number of mistakes=y (a) When you test the claim at the α = 0.01, that a linear relation exists between the two variables, find the critical value. Round critical value to nearest hundredth. (e.g. 0.135 would be entered as 0.14, -0.135 would be entered as -0.14, ± 0.135 would be entered as +/-0.14).
