Refer to Exercise 6.14 and find the probability that the observed May rainfall will fall within two standard deviations of the mean May rainfall.
Answer to relevant QuestionsExplain what the mean, μ, tells us about a normal curve, and explain what the standard deviation, σ, tells us about a normal curve. Suppose that the random variable x is normally distributed with mean m 1,000 and standard deviation s 100. Sketch and find each of the following probabilities: a. P(1,000 ≤ x ≤ 1,200) b. P(x > 1,257) c. P(x < 1,035) ...A filling process is supposed to fill jars with 16 ounces of grape jelly. Specifications state that each jar must contain between 15.95 ounces and 16.05 ounces. A jar is selected from the process every half hour until a ...Suppose that x has a binomial distribution with n = 200 and p = .4. a. Show that the normal approximation to the binomial can appropriately be used to calculate probabilities about x. b. Make continuity corrections for ...Repeat Exercise 6.48 with λ= 3 In Exercise 6.48 Suppose that the random variable x has an exponential distribution with 2. a. Write the formula for the exponential probability curve of x. What are the possible values of x? ...
