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 the syndicated panels. Syndicated

Answer:
answer is b) False
Explanation:
given data
contribution margin = $10
selling price = $25
total fixed costs = $500
break-even point = 100 units
solution
we get here Break even point that is
Break even point = 
...........1
Break even point = 
Break even point = 50 units
but we have given break-even point is 100 units
so answer is b) False
