Chapter 10: HYPOTHESIS TESTING WITH TWO SAMPLE
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
Yes. This decision is based on sufficient evidence. There is adequate information to determine that the proportion (percent) of the population in Nevada who is of 
or more races is statistically higher than in North Dakota at the 
significance level.
Yes. This conclusion can be drawn based on the evidence.
