using the Central limit Therorem to find the mean and the standard error of the sample mean of the sample distribution. Then sketch a graft of the sampling. The mean price of the photo printers on the website is $ 242 with a standard deviation of $ 69. Random samples are of size 33 are drawn from this population and the mean of each sample is determined what is the standard deviation of the distribution of the sample mean is?

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
