Sampling by accountants Accountants often use stratified samples during audits to verify a company’s records of such things as accounts receivable. The

stratification is based on the dollar amount of the item and often includes 100% sampling of the largest items. One company reports 5000 accounts receivable. Of these, 100 are in amounts over \(50,000;500 are in amounts between \)1000and\(50,000; and the remaining 4400are in amounts under \)1000Using these groups as strata, you decide to verify all the largest accounts and to sample 5% of the midsize accounts and 1%of the small accounts. How would you label the two strata from which you will sample? Use Table D, starting at line 115 to select only the first3 accounts from each of these strata.

Child care and aggression A study of child care enrolled 1364infants and followed them through

their sixth year in school.

(a) Is this an observational study or an experiment? Justify your answer.

(b) What are the explanatory and response variables?

(c) Does this study show that child care causes children to be more aggressive? Explain.

Apply Brand X weed killer to all 12of those plants.

Apply Brand Y weed killer to the remaining 12plants.

Plan B: Choose 12of the 24plants at random. Apply

Brand X weed killer to those 12plants and Brand Y

weed killer to the remaining 12plants.
