Question

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2017, 9 of the 30 stocks making up the DJIA increased in price.
On the basis of this fact, a financial analyst claims we can assume that 68% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day. A sample of 55 stocks traded on the NYSE that day showed that 35 went up. You are conducting a study to see if the proportion of stocks that went up is significantly different from 68%. You use a significance level of α=0.05α=0.05.

The null and alternative hypotheses would be:
  H0H0: ? μ p  Select an answer = < > ≠   (please enter a decimal)
  H1H1: ? μ p  Select an answer < = ≠ >   (Please enter a decimal)

The test statistic = (please show your answer to 3 decimal places.)

The p-value = (Please show your answer to 4 decimal places.)

The p-value is ? > ≤ αα
