This test: 20 point(s) p This question: 1 point A data set lists weights (Ib) of plastic discarded by households. The highest weight is 5.34 lb, the mean of all of the weights is x = 2.007 lb, and the standard deviation of the weights is s = 2.091 lb. a. What is the difference between the weight of 5.34 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 34 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 5.34 lb significant? a. The difference is (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
