Part I: Probability For each of the following problems, you should write your answer as an expression. Do not give the final numeric value. For example, you should write C(4,2)/24 instead of 0.375. 5. You are playing Scrabble and you draw seven tiles: M, A, T, C, H, E, S. You line them up in some random order on your tile rack (assume all orderings are equally likely). The events M, T, and S are defined as follows: M: The tiles M, A, T, H appear consecutively. T: The tile T appears exactly in the middle (fourth position). S: The tile S is either in the first position or in the final position. Calculate the probability of each event; that is, p(M), p(T), and p(S). 5.1 5.2 What is p(MIT)? 5.3 What is p(MIS)? 5.4 5.5 What is p(T|S)? Consider all pairs of events: (M,T), (M,S), and (T,S). Which pairs of events are independent and which pairs of events are not independent? Justify your answer.

In a computer game, different units are created randomly with different levels of range and Aggression according to the table below. Range is how far the unit can attack without moving, and Aggression is used to determine how far a unit will move to attack without direct command.

Researchers are wondering whether they can predict college GPA with the number of hours studying per week. To test this, they randomly select 8 college students, record their GPA and the number of hours spent studying per week. GPA 2.5 2.7 3.4 3.7 2.7 1.9 2.0 4.0 ID 1 2 3 4 5 6 7 8 Hours studying per week 25.0 27.6 30.2 35.0 31.6 25.6 30.0 40.0 Based on the information in the table above, the researchers compute the regression equation: Y = -0.970 + 0.125 X. Do the researchers have enough evidence to claim that the number of hours studying predicts students' GPA? Based on the analysis, what would be the predicted GPA for someone who studies 30 hours per week? O2.00 O Cannot be predicted. O 1.25 2.78

Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 8 adults. The following table presents the results.

Understanding hypothesis tests in general: One use of a Chi-square test is to determine whether factors are independent from each other or dependent on each other. For example, consider the following: A marketer, who works for a brewery, has to promote a new beer. She samples 150 people and wants to determine whether there is an association between gender and beer preference. If there is an association, then it means that a persons beer preference can be predicted by knowing the persons gender. The results are: Beer preference Gender Light ale Lager Best bitter Total Male 20 40 20 80 Female 30 30 10 70 Total 50 70 30 150 The null hypothesis always says that the factors are independent, i.e. H0: Beer preference and Gender are independent The alternative hypothesis always says the opposite, i.e. H1: Beer preference and Gender are dependent The hypothesis test was performed at the 2.5% level of significance and the p-value was found to be 0.0149.
