Answer:
This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreaseddecreased because belowbelow 0.10 because the proportion of sample, is nothing very close to 0.10.
Explanation:
n = 1100
p = 0.10
Using the formula np(1-p), we will have
= 1100(0.10)*(1 - 0.10)
= 1100*0.10*0.90
= 99
99 ≥ 10
This satisfies normal distribution condition. That is, proportion of sample are normally distributed.

The correct answer is A. During 2009 real GDP in Viloxia grew by 2 percent, which is about the same as average U.S. growth over the last one-hundred years.
Given that in 2009, the imaginary nation of Viloxia had a population of 5,000 and real GDP of 500,000, and in 2010 it had a population of 5,100 and real GDP of 520,200, to determine the growth of real GDP in Viloxia during 2009, the the following calculations must be made:
- Total GDP / population = real GDP
- 500,000 / 5000 = X
- 100 = X
- 520,200 / 5100 = X
- 102 = X
- 102 - 100 = 2
Therefore, during 2009 Viloxia's GDP grew by 2 percent, which is about the same as average U.S. growth over the last one-hundred years.
