A spaceship is designed to support animal life for a multiyear voyage to the outer planets of the solar system. Plants will be grown to provide oxygen and to recycle carbon dioxide. Since the spaceship will be too far from the sun for photosynthesis, an artificial light source will be needed. Suppose a plant has a unique photosynthetic pigment and the leaves of this plant appear to be reddish yellow. What wavelengths of visible light are absorbed by this pigment?

Two companies start out interdependent, but they merge. When Beta Company acts, it affects Gamma Industries. Beta has two actions, A and B. Gamma has two actions D and E. I’ll present the payoffs:                  Beta     A B Gamma D $27/ $8 $20 / $15 E $18/ $19 $11/ $18 If Beta chooses A and Gamma chooses D then Beta gets $8 and Gamma gets $27. If Beta chooses A and Gamma chooses E then Beta gets $19 and Gamma gets $18. The other cells can be interpreted similarly. The payoffs are common knowledge and Beta and Gamma are rational in the sense of being good predictors of each other’s actions.  Beta and Gamma are maximize their own payoffs. Once firms merge and are subject to a single decision maker, what actions will they take?

There are situations where activities do not get the same level of scrutiny if they seem to be small.  From the headlines: Situation 1. The indictment alleges that , using her position would split contract requests from one contract into multiple, smaller contracts, in order to avoid threshold amounts that would trigger a formal, competitive bidding process.    To meet the Department of Education requirement that such an informal bid have at least two competing vendor quotes for comparison, would obtain false and inflated quotes, by herself and from the other conspirators, designed to make the intended conspirator’s business the lower bid, and to guarantee the award of the contract.  Situation 2. also knew that its outside auditors only questioned additions to fixed asset accounts at any particular facility if the additions exceeded a certain dollar threshold. Thus, when artificially increasing at a particular facility, HRC was careful not to exceed the threshold.   In Situation 1, a manager would split contracts into smaller units where the bids did not need the same level of scrutiny.  This allowed the manager to funnel the contracts to associates.  In Situation 2, a manager kept the artificial transactions below a dollar limit, because the auditors would not look at small transactions. Required: a. Which category of objective(s) is involved with Situation 1, Operations, Reporting, or Compliance? b. Which category of objective(s) is involved with Situation 2, Operations, Reporting, or Compliance? c. What can be done to prevent or detect frauds that are individually small, but add up?  I’m asking you for a bit of speculation on what organizations can do.  Incidentally, in both cases, the fraud came to light, but only after they had some effect.

17. (2 points) For the data set: Old Dies: 8000, 12500; New Dies: 7000, 8500, 5000 The above data is the number of cycles to failure of old die-cast automotive parts versus new die-cast parts. My hypothesis is that the new dies don’t last as long as the old dies (i.e.

A set of data contains n paired observations (Xi; Yi); i = 1 …  n. The Spearman correlation is 0.7. If all the Xi are multiplied by 10, what is the resulting Spearman correlation?

Consider the following data set: 2.2, 2.3, 2.3, 2.5, 2.6, 2.7, 2.7, 2.7, 2.8, 2.9,  3.1, 3.2, and 3.5. The rank assigned to the three observations of value 2.7 is
