QUESTION 7 The continuity correction factor allows us to approx create the interval of interest True O False mate the binomial distribution with the exponential distibution by adding and subtracting the value 0.5 to QUESTION 8 Bananas are sold in bunches at a grocery store and typically consist of 4-8 bananas per bunch. Suppose the weight of these bunches tion with a mean of 3.54 pounds and a standard deviation of 0.63 pounds. What is the probability that a randomlý selected bunch of bananas will weigh less than 4.0 pounds? O 0.5080 O 0.6808 O 0.7673 0.9821 QUESTION 9 The shape of the uniform probability distribution is O symmetrical O left-skewed. O right-skewed. O flat. 2 points Save Suppose the average tread-life of a certain brand of tire is 42,000 miles and that this mileage folows the exponential probability distribution. What is the probability that a randomly selected tire will have a tread-life between 30,000 and 50,000 miles? QUESTION 10 0.1854

Explanation / Answer

(7) False, since the approximation is not to the exponential distribution, but to the normal distribution.

(8) Prob. (X <= 4) = Prob. (Z <= 0.7302) = 0.7673.

(9) Shape of uniform distribution = flat.
