An entrepreneur owns some land that he wishes to develop. He identifies two development options: build condominiums or build apartment buildings. Accordingly, he reviews public records and derives the following summary measures concerning annual profitability based on a random sample of 34 for each such local business venture. For the analysis, he uses a historical (population) standard deviation of $21,900 for condominiums and $19,600 for apartment buildings. (You may find it useful to reference the appropriate table: z table or ttable) Sample 1 represents condominiums and Sample 2 represents apartment buildings. Condominiums I = $252,000 ni = 34 Apartment Buildings I2 = $235,600 n2 = 34 a. Set up the hypotheses to test whether the mean profitability differs between condominiums and apartment buildings. Ho: 41- 42 = 0; HA H1- 42 * 0 O Ho: 41- 42 20; HA -42<0 O Ho: 41- 42 S 0; HA 1- H2>0 b. Calculate the value of the test statistic. (Round final answer to 3 decimal places.) O Answer is complete but not entirely correct. Test statistic 0.0080 X
