Part 2) Kitchen   
length (16 ft)  -------------> [blueprint]=(1/4)*16=4 in
width (16 ft) ----------------> [blueprint]=(1/4)*16=4 in

Part 3) Office   
length (8 ft)  -------------> [blueprint]=(1/4)*8=2 in

According to a study conducted by an​ organization, the proportion of Americans who were afraid to fly in 2006 was 0.10. A rando
Nimfa-mama [501]

Answer: No, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.

Step-by-step explanation:

Since we have given that

n = 1400

x = 154

So, \hat{p}=\dfrac{154}{1400}=0.11

and p = 0.10

So, hypothesis would be

H_0:\hat{p}=p\\\\H_a:\hat{p}>p

So, the test statistic value would be

z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\z=\dfrac{0.11-0.10}{\sqrt{\dfrac{0.1\times 0.9}{1400}}}\\\\z=\dfrac{0.01}{0.008}\\\\z=1.25

At 5% level of significance,

critical value would be 1.96.

Since 1.96>1.25.

so, we will accept the null hypothesis.

Hence, no, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
