Do rats take less time on average than hamsters to travel through a maze? The table below shows the times in seconds that the rats and hamsters took. Rats: 26, 46, 28, 37, 21, 11, 37, 25 Hamsters: 40, 47, 53, 39, 37, 49, 12, 33 Assume that both populations follow a normal distribution. What can be concluded at the c = 0.05 level of significance level of significance? For this study, we should use t-test for the difference between two independent population means Ho: p1 E8 a. The null and alternative hypotheses would be: H₂ : 1 8 b. The test statistic t c. The p-value = u2 p2 (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.)

5. A B Suppose that P(A)=0.4, P(B)=0.5 and P(AUB) = 0.42. Are A and B independent? Yes, A and B are independent. No, A and B are not independent.

30. Using the picture, find the value of a and b.
