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.

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, 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 76 stocks traded on the NYSE that day showed that 27 went up.
You are conducting a study to see if the proportion of stocks that went up is significantly more than 0.3.
You use a significance level of a = 0.01.
What is the test statistic for this sample? (Report answer accurate to three de
ecimal places.)
test statistic = 2.78
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value = 0.0054
