22. In an extensive study involving thousands ofBritish children, Arden and Plomin (2006) foundsignificantly higher variance in the intelligencescores for males than for females. Following agehypothetical data, similar to the results obtainedin the study.

K A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.26 lb, the mean of all of the weights is x=2.312 lb, and the standard deviation of the weights is s = 1.118 lb. a. What is the difference between the weight of 5.26 lb and the mean of the weights? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the weight of 5.26 lb to a z score. d. If we consider weights that convert to z scores between 2 and 2 to be neither significantly low nor significantly high, is the weight of 5.26 lb significant? a. The difference islb.
