The state of Delaware has studied a large population of pregnant women applying for maternity leave. The women stated which trimester of their pregnancy ( 2, or 3) they are in. The mean response was j = 2.71, with a standard deviation of o = 0.43. Suppose that we will take a random sample of n =7 of these women's responses. Let x represent the sample mean of the 7 women's responses. Consider the sampling distribution of the sample mean x. Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed. (a) Find - (the mean of the sampling distribution of the sample mean). (b) Find o- (the standard deviation of the sampling distribution of the sample mean). O- =
