Given information
Use the following information to answer the next twelve exercises. In the recent Census, three percent of the U.S. population reported being of two or more races. However, the percent varies tremendously from state to state. Suppose that two random surveys are conducted. In the first random survey, out of North Dakotans, only nine people reported being of two or more races. In the second random survey, out of Nevadans, people reported being of two or more races. Conduct a hypothesis test to determine if the population percents are the same for the two states or if the percent for Nevada is statistically higher than for North Dakota.
Step-by-step explanation
Since, the hypothesis involves the proportions, therefore
The normal distribution is used to test the proportions of the sample for this hypothesis test.
