22 The average age for licensed drivers in the country is u = 42.6 years with a standard deviation of = 12. The distribution is approximately normal
a. A researcher obtained a sample of n = 25 drivers who received parking tickets. The average age
for these drivers was M = 40.5. Is this a reasonable outcome of a sample of n=25, or is the sample
mean very different from what would normally be expected? (Hint: Compute the z-score for the
sample mean )
b. The same researcher also obtained a sample of n = 12 drivers who received speeding tickets. The
average age for this sample was M = 34.4. Is this a reasonable outcome for a sample of n= 16, or is
the sample mean very different from what would usually be expected? (Again, compute the z-score
for the sample mean.)​

< back to assignment attempts: 1 1 keep the highest: 1 / 2 2. determining opportunity cost juanita is deciding whether to buy a suit that she wants, as well as where to buy it. three stores carry the same suit, but it is more convenient for juanita to get to some stores than others. for example, she can go to her local store, located 15 minutes away from where she works, and pay a marked-up price of $102 for the suit: store travel time each way price of a suit (minutes) (dollars per suit) local department store 15 102 across town 30 88 neighboring city 60 65 juanita makes $42 an hour at work. she has to take time off work to purchase her suit, so each hour away from work costs her $42 in lost income. assume that returning to work takes juanita the same amount of time as getting to a store and that it takes her 30 minutes to shop. as you answer the following questions, ignore the cost of gasoline and depreciation of her car when traveling. complete the following table by computing the opportunity cost of juanita's time and the total cost of shopping at each location. store opportunity cost of time price of a suit total cost (dollars) (dollars per suit) (dollars) local department store 102 across town 88 neighboring city 65 assume that juanita takes opportunity costs and the price of the suit into consideration when she shops. juanita will minimize the cost of the suit if she buys it from the . grade it now save & continue continue without saving

The east asiatic company (eac), a danish company with subsidiaries throughout asia, has been funding its bangkok subsidiary primarily with u. s. dollar debt because of the cost and availability of dollar capital as opposed to thai baht-denominated (b) debt. the treasurer of eac-thailand is considering a 1-year bank loan for $247,000.the current spot rate is b32.03 /$, and the dollar-based interest is 6.78% for the 1-year period. 1-year loans are 12.04% in baht. a. assuming expected inflation rates of 4.3 % and 1.24% in thailand and the united states, respectively, for the coming year, according to purchase power parity, what would the effective cost of funds be in thai baht terms? b. if eac's foreign exchange advisers believe strongly that the thai government wants to push the value of the baht down against the dollar by5% over the coming year (to promote its export competitiveness in dollar markets), what might the effective cost of funds end up being in baht terms? c. if eac could borrow thai baht at 13% per annum, would this be cheaper than either part (a) or part (b) above?
