Answer Date: ZTIUSIZDZU a) The explanatory variable is driving experience due to driving experience does not impact monthly premium cost of insurance policies. The response variable is monthly premium due to monthly premiums depend on driving experience. Higher driving experience is leads to lower monthly In'emiums cost of insurance policies and lower driving experience is leads to higher monthly premiums cost of insurance policies. 13) A scatterplot of monthly premiums [3!) on driving experience (I) is, By using MINTI'AB software, draw the scatterplot with the help of following steps: 1) Import the given data into worksheet. 2) Select Seatterplot from the Graph. 3) Choose Simple graph options and click 0k. 4) Select the X variables and Y variables. 5) Click 0k. Quiz 5.6 (A) Random variables X and Y in Example 5.3 and random variables Q and G in Quiz 5.2 have joint PMFs: Px, Y(x, y) y=0 y=1 y=2 Po.(q, g) 9=0 9=1 g=2 g=3 T=U 0.01 0 0 9 =0 0.06 0.18 0.24 0.12 0.09 0.09 0 9 =1 0.04 0.12 0.16 0.08 T = 2 0 0 0.81 (a) Are X and Y independent? (b) Are Q and G independent? (B) Random variables X1 and X2 are independent and identically distributed with probability density function 1x/2 05x52, (5.43) fx (x) = 10 otherwise. What is the joint PDF fx1,x2(1, 12)?Random variables X and Y are independent exponential random variables with E[X] = E[Y] = Find the PDF of W = X + Y. W 20 fw(W) = 0 otherwise
