Question
A motorcycle drives from Welcome Rotonda to Fairview and back using the same course everyday. There are four stoplights on the course. Let x denote the number of red lights the motorcycle encounters going from Welcome Rotonda to Fairview and y denote the number encountered on the return trip. Data collected over a long period suggest that the joint probability distribution for (x, y) is given by 3 0.07 1 2 4 001 0.01 0.05 0.03 0.01 0.02 0.01 0.01 0.01 1. 0.03 0.08 0.03 0.01 0.03 2. 0.03 0.11 0.15 3. 0.02 0.07 0.1 0.01 0.06 0.03 0.01 0.01 (a) Give the marginal probability distribution of fx (0).

Answer= (f) Give EX| Y = 3). Answer= E) Give the standard deviation of Y, Answer *Complete the interpretation of the data. As the number of from Welcome Rotonda to Fairview encountered by the motorcycle increases, the number of stoplights of its return trip tends to (increase, decrease, or be uncorrelated). Therefore, Xand Y have a (zero, negative, or positive) covariance. The covariance was calculated to be (numerical value). *Describe the correlation whether a strong a weak, or no. Xand Y have correlation. What is the correlation value? =
