Asimple random sample of size n=46 is obtained from a population with μ=64 and σ=15.

a) what must be true regarding the distribution of the population in order to use the normal model to compute probabilities involving the sample mean?

Arandom sample of size n 64 is taken from a population with population proportion p 0.38 describe the sampling distribution of p. draw a graph of this probability distribution with its a. mean and standard deviation. b. what is the probability that the sample proportion is greater than 0.5? what is the probability that the sample proportion is less than 0.3? d. what is the probability that the sample proportion is between 0.35 and 0.45?
