Smith Jones CPA was auditing the financial statements of Titan Industries. When auditing accounts receivable, he realized the population was diverse and could be divided into two "separate" smaller populations. There were 5 accounts receivable that in total were $10,000. The remaining 45 account receivable balances totalled $17,000. Smith Jones was concerned that a random sample of the entire population would miss many of the 5 balances that totalled $10,000 but did not want to eliminate the possibility of testing many of the other 45. He decided to consider a stratified sample.1. Why did Smith Jones CPA consider stratifying the population?
2. Why didn't Smith Jones CPA choose to sample from the population as a whole?
3. Why is it important to not "skip" sampling the other 45 balances?

Susie buys two goods - rounds of golf and massages. suppose that the price of a round of golf is $20, and the price of a massage is $30. in a typical week susie will play two rounds of golf, getting 20 units of satisfaction from the second round. she normally buys three massages each week, with the third giving her 30 units of satisfaction. if she were to buy a fourth massage in a week, it would give her 20 units of satisfaction. if the price of massages is reduced to $15, which of the following outcomes might we expect to occur? a) susie would leave her consumption choices unchanged because of diminishing marginal utility in the consumption of massages. b) susie would buy more massages and more rounds of golf, as predicted by the substituion effect. c) susie would buy more massages and fewer rounds of golf, as predicted by the substitution effect. d) susie would buy more massage and fewer rounds of golf, as predicted by income effect.
