  1. Use this table, which details how Pay Pal's employees commute to work, to answer all parts of this question.

    1. Car Bus Train Total
      Management 14 21 11 46
      Labor 51 107 165 323
      Total 65 128 176 369

      Part 1 of 2:

      Give the marginal distribution of mode of transportation (to the nearest tenth of a percent) . Be sure to label each with the percent sign!

      Car =

      Bus =

      Train =

      Give the conditional distribution of mode of transportation for those in management (to the nearest tenth of a percent). Be sure to label each with the percent sign!

      Car =

      Bus =

      Train =

      Give the conditional distribution of mode of transportation for those in labor (to the nearest tenth of a percent) .   Be sure to label each with the percent sign!


      Car =

      Bus =

      Train =

      Based on the data above, "Job Class" and "Mode of Transportation" Blank 10 (do/do not) appear to be independent

Please answer all parts of the question, with all work shown Suppose there are 300 cards in a box numbered 1 through 300. Therefore, the number of each card has one, two, or three digits. A card is drawn at random from the box. Suppose that the number on the card has X digits of which Y are 0. Suppose we would like to know whether X and Y are correlated, negatively correlated, or uncorrelated. Determine Cov(X,Y)Cov(X,Y) and ρ(X,Y)ρ(X,Y), hence...
