You found a public database for hedge fund returns and are eager to do some data analyses on hedge funds in general using the database. Your colleague found out that the hedge funds in the database were under no pressure to report their performance to anyone outside the funds. Based on her finding, she argues that the returns in the public data are likely to be biased upward. Would you agree? Why or why not? Briefly explain.

At December 31, 2017, Grand Company reported the following as plant assets.
| Land | $ 4,320,000 | |||
| Buildings | $29,800,000 | |||
| Less: Accumulated depreciation—buildings | 10,570,000 | 19,230,000 | ||
| Equipment | 47,520,000 | |||
| Less: Accumulated depreciation—equipment | 4,910,000 | 42,610,000 | ||
| Total plant assets | $66,160,000 |
During 2018, the following selected cash transactions occurred.
| April 1 | Purchased land for $2,000,000. | |
| May 1 | Sold equipment that cost $840,000 when purchased on January 1, 2014. The equipment was sold for $504,000. | |
| June 1 | Sold land purchased on June 1, 2008 for $1,430,000. The land cost $393,000. | |
| July 1 | Purchased equipment for $2,440,000. | |
| Dec. 31 | Retired equipment that cost $480,000 when purchased on December 31, 2008. The company received no proceeds related to salvage. |
A: Journalize the above transactions. The company uses straight-line depreciation for buildings and equipment. The buildings are estimated to have a 50-year life and no salvage value. The equipment is estimated to have a 10-year useful life and no salvage value. Update depreciation on assets disposed of at the time of sale or retirement.
B: Record adjusting entries for depreciation for 2018.

A 5.274 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 11.99grams of CO2 and 4.909 grams of H2O are produced.
In a separate experiment, the molar mass is found to be
116.2 g/mol. Determine the empirical formula and
the molecular formula of the organic compound.
