According to an August 26, 2008, press release from the U.S. Census Bureau News, the median household income in 2007 was $50,023. A random sample of 250 incomes has a median value different from that of any of the 250 incomes in the sample. The data contain 105 runs above and below the median. Use this information to test the null hypothesis that the incomes in the sample form a random sequence with respect to the two properties above and below the median value versus the alternative, that the sequence is not random at a = 0.05. .
