Let x be a continuous random variable that follows a distribution skewed to the left with μ = 86 and o = 15. Assuming < 0.05, find the probability that the sample mean, x, for a random sample of 69 taken from this n N population will be a. less than 83.9. Round your answer to four decimal places. P(less than83.9) b. greater than 87.9. i

n Let x be a continuous random variable that follows a distribution skewed to the left with μ = 86 and o = 15. Assuming ≤ 0.05, find the probability that the sample mean, x, for a random sample of 69 taken from this N population will be a. less than 83.9. Round your answer to four decimal places. P(less than83.9) = i b. greater than 87.9. Round your answer to four decimal places. P(greater than 87.9) = i
