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 is significantly less than 0.3.

Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Transcribed Image Text: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 less than 0.3.
- ○ There is not sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is less than 0.3.
- ○ The sample data support the claim that the proportion of stocks that went up is less than 0.3.
- ○ There is not sufficient sample evidence to support the claim that the proportion of stocks that went up is less than 0.3.

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...
