Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.

A sample of 59 stocks traded on the NYSE that day showed that 8 went up.

You are conducting a study to see if the proportion of stocks that went up is significantly less than 0.3. You use a significance level of \( \alpha = 0.001 \).

What is the test statistic for this sample? (Report answer accurate to three decimal places.)

Test statistic = [ ]

What is the p-value for this sample? (Report answer accurate to four decimal places.)

p-value = [ ]

The p-value is...

- [ ] less than (or equal to) \( \alpha \)
- [ ] greater than \( \alpha \)

This test statistic leads to a decision to...

- [ ] reject the null
- [ ] accept the null
- [ ] fail to reject the null
