In 2022 it wаs estimаted thаt 26% оf Americans whо are 18 - 29 years оld are on track for saving for retirement. To see if that has changed, an financial advisor chooses a random sample of 1250 of Americans in this age group. 1. Assuming that the 26% is correct, what is the mean and standard deviation in the number of visitors in groups of 1250 that would be expected to be on track for saving for retirement? Where rounding is necessary, round to one decimal places. Mean = [mean] visitors Standard deviation = [sd] visitors 2. Describe the sampling distribution of the sample proportion for samples of size n = 1250 The sampling distribution is [norm] with a mean
