Consider a population of size=9,800. with a mean of U with the tail in front on u =161 and a standard deviation of o with the tail on front of o =17. compute the following z values for either the population distribution or the sampling distributions of x with the - on top of x with given sample size. round solutions to two decimal places, if necessary. Suppose a random single observstion is selected from the population. calculate the z value that corresponds to x =165 z= Suppose a random single observations is selected from the population. calculate the z value that corresponds to x=157 z=
