A student pulls out a marble from a bag containing blue, green, and red marbles. He records the color and places it back into the bag. The table below shows the frequency of each color after 100 marbles are pulled out: Color of Marbles Blue Green Red
Number of Draws 13 29 58

How many green draws can you expect if the marbles are pulled out 1,000 times?

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
