1. A sports scientist collects strength data from two groups of students. The first group is a group of athletes who might be expected to be strong, and the second group is a control group of nonathletic students. The first group has strength ratings of: c(129.4, 111.8, 127.7, 130, 120.7, 118.2, 121.9) And the second group has strength ratings of: c(149.1, 111.6, 122.1, 126.4, 123.3, 105.5, 127.3, 101.2, 113.3 ) Is there evidence that the first group is actually stronger than the second?

(a) State a sensible null hypothesis

(b) Is a one-sided or two-sided test needed? justify

A firm sells its product to two groups of customers. Demand from group 1 is Q1 = 100, 000− 5,000P and demand from group 2 is Q2 = 140,000 − 10,000P. a) Find the total demand that the firm faces for its product. Explain it first using pictures, and then do the algebra. Write your answer of the total demand as quantity as a function of price. (Hint: draw pictures. Then add the two demands horizontally; that is, at each...

College students were randomly sorted into one of two groups. Members of each group performed a series of mental tasks while music was playing in the background. One group listened to pop music and the other to country music. It is hypothesized that music will effect the number of tasks completed. What can be concluded with an α of 0.10? The results are below: pop country 1 = 39.31 1 = 5.43 n1 = 10 2 = 44.15 2 =...
