1. The following data show the number of days
it took to close the sale of twenty homes for a particular lending
institution. Compute the mean, median, standard
deviation and % coefficient of variation. Are there any
outliers (any values that exceed the mean by more than 3 standard
deviations)? If the expected value for the mean is 30
days, what is the percent bias and the sign? (12
points)
