A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.73 lb, the mean of all of the weights is x = 2.316 lb, and the standard deviation of the weights is s = 1.967 lb. a. What is the difference between the weight of 5.73 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 5.73 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 5.73 lb significant? a. The difference is lb. (Type an integer or a decimal. Do not round.) b. The difference is standard deviations. (Round to two decimal places as needed.) c. The z score is z = (Round to two decimal places as needed.) d. The highest weight is not significant. significantly high. significantly low.
