3.An instructor has given a short quiz consisting of two parts. For a randomly selected student, letX = the number of points earned on the first part and Y= the number of points earned on the secondpart. Suppose that the joint PMF of X and Y is given in the accompanying table.X5Y0100.060.150.1500.020.1250.040.30100.010.15Let Z represents the score recorded in the grade book which is the total number of points earnedon the two parts, what is the PMF of Z?

To find the PMF of Z, where Z = X + Y, we need to sum the probabilities of all possible combinations…

Consider ratings of 4 “Agree” or 5 “Strongly Agree” to mean that test takers have obtained a “high” score on a BRS item. Ratings of 1-3 would be considered “low” item scores. Compute the item discrimination index (d) for BRS Item 3. Enter the values below that you obtain from Excel: Total # of test takers N = _______ 25% of the total # of test takers, or # in the Upper 25% group U = _______ # of test takers in the Upper 25% group for BRS total scores who scored high on item 3 = _______ # of test takers in the Lower 25% group for BRS total scores who scored high on item 3 = _______ Item discrimination index d = ________ ID # Item 1 Item 2 Item 3 Item 4 Item 5 Item 6 BRS Total Score 25 5 5 5 5 5 5 55 24 5 5 2 4 5 5 50 21 5 4 5 3 5 5 48 22 5 5 4 3 3 4 46 23 5 3 3 5 5 2 46 18 4 5 5 4 4 4 44 20 5 5 4 3 3 4 44 16 5 4 5 5 4 3 42 19 4 5 4 1…
In a study of exhaust emissions from school buses, the pollution intake by passengers was determined for a sample of nine school buses used in the Southern California Air Basin. The pollution intake is the amount of exhaust emissions, in grams per person, that would be inhaled while traveling on the bus during its usual 18-mile trip on congested freeways from South Central LA to a magnet school in West LA. Here are the amounts for the nine buses when driven with the windows open. 1.17 0.33 0.40 0.33 1.32 0.38 0.25 0.40 0.35 (a) Consider making a stemplot. Are there outliers or strong skewness that would preclude use of the t procedures? Which is correct? A. The sample is small and the stemplot is right skewed with possible outliers, so use of t procedures is not appropriate. b. The distribution is symmetric so use of t procedures is appropriate. c. The sample is small and the stemplot is left skewed with possible outliers, so use of t procedures is…
Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
