Suppose pages per book in a library have an unknown distribution with mean 297 and standard deviation 25 pages. a sample of size n=75 is randomly taken from the population and the sum of the values is taken. using the central limit theorem for sums, what is the standard deviation for the sample sum distribution?

What is the probability of throwing several dice with sum equal to 6 (six)? show the ways of possibilities for sum 6 (as the numerator) and the ways of throwing n dices for n = 1, 2, 3, 4 or 5 as denominator for all the questions to earn full credits. (a)throw one die, (b) throw two dice, (c) throw three dice (d) throw 4 dice, (e) throw 5 dice
