Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good baromet 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 assu that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day. A sample of 73 stocks traded on the NYSE that day showed that 14 went up. You are conducting a study to see if the proportion of stocks that went up is less than 0.3. You use a significance level of 0.005

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 73 stocks traded on the NYSE that day showed that 14 went up.
You are conducting a study to see if the proportion of stocks that went up is less than 0.3. You use a
significance level of a =
0.005.
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...
O less than (or equal to) a
greater than a
This test statistic leads to a decision to...
O reject the null hypothesis
accept the null hypothesis
fail to reject the null hypothesis
As such, the final conclusion is that...
is
There is enough evidence to show rejection of the claim that the proportion of stocks that went
less than 0.3.
dn
O There is not enough evidence to show rejection of the claim that the proportion of stocks that went up
is less than 0.3.
OThere is enough evidence to show that the proportion of stocks that went up is less than 0.3.
There is not enough evidence to show that the proportion of stocks that went up is less than 0.3.
