A company has 4 employees named Joe, Steve, Mary, and Alice (abbreviate the names J,S,M, and A). The company randomly selects two employees to be part of a committee. Joe and Steve are males, while Mary and Alice are females. The sample space for this is: S = {(J, S),(J, M),(J, A),(S, M),(S, A),(M, A)}. Denote the following events: A = the event/set of picking exactly one female. B = the event/set of picking at least 1 female. a. Write out the event/set A b. Write out the event/set B c. List the outcomes/elements in the event A^c. d. List the outcomes/elements in the event A ∩ B

A group of 11 students was selected at random and asked for their high school GPA and their freshmen GPA in college the subsequent year. The results were: Student High School GPA Freshmen GPA 1 2.0 1.6 2 2.2 2.0 3 2.6 1.8 4 2.7 2.8 5 2.8 2.1 6 3.1 2.0 7 2.9 2.6 8 3.2 2.2 9 3.3 2.6 10 3.6 3.0 We would like to know whether there is a linear relationship between the high school GPA and the college freshmen GPA, and we would like to be able to predict the freshmen GPA, if we know that the high school GPA of another student is, say, 3.4.  Provide the two requested scatter plots for this data (put college freshman GPA on the Y (vertical) axis!).  a) What would be your approximate 95% prediction interval for question (g)? b) Show your scatterplot with the predicted trend line below
