In words, X = _____________X ~ _____(_____,_____)μ x = _____σ x = _____In words, X ¯ = ______________X ¯ ~ _____(_____,_____)In words, ΣX = _____________ΣX ~ _____(_____,_____)Without doing any calculations, do you think that it’s likely that the professor will need to read a total of more than 1,050 pages? Why?Calculate the probability that the professor will need to read a total of more than 1,050 pages.Why is it so unlikely that the average length of the papers will be less than 12 pages?
