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 79 stocks traded on the NYSE that day showed that 33 went up.

You are conducting a study to see if the proportion of stocks that went up is is significantly more than 0.3. You use a significance level of α=0.002.

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) αα
  • greater than α

This test statistic leads to a decision to...

  • reject the null
  • accept the null
  • do not reject the null

As such, the final conclusion is that...

  • There is sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is more than 0.3.
  • There is not sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is more than 0.3.
  • There is evidence to support the claim that the proportion of stocks that went up is more than 0.3.
  • There is not evidence to support the claim that the proportion of stocks that went up is is more than 0.3.

A survey claims that the average cost of a hotel room in Atlanta is more than $125.50 per night. To test this claim, a researcher selects a random sample of 55 hotel rooms and finds that the mean cost per night is $130.75. The standard deviation of the population, σ, is known to be $2.50. At a = 0.05, is there enough evidence to support the claim?

A survey found that​ women's heights are normally distributed with mean 63.1 in. and standard deviation 2.3 in. The survey also found that​ men's heights are normally distributed with mean 69.6 in. and standard deviation 3.4 in. Most of the live characters employed at an amusement park have height requirements of a minimum of 57 in. and a maximum of 62 in. Complete parts​ (a) and​ (b) below.

a. Find the percentage of men meeting the height requirement. What does the result suggest about the genders of the people who are employed as characters at the amusement​ park?

b. If the height requirements are changed to exclude only the tallest​ 50% of men and the shortest​ 5% of​ men, what are the new height​ requirements? The new height requirements are a minimum of ? in. and a maximum of ? in.
