Does the Dow Jones Industrial Average (DJIA) fluctuate randomly from quarter to quarter? (A quarter refers to a quarter of the year. For example, January-March is the first quarter.) A stock analyst selected 40 consecutive quarters and computed the percentage change in the DJIA. He indicated positive percentage changes with a P and negative percentage changes with an N. The following are the results. Conduct a runs test for randomness on the sequence of quarterly market fluctuations at the α = 0.05 level of significance.
