Answer:
62.28
Step-by-step explanation:
Ok, so since we know the radius of the circle and the area of the shaded region, we can find the fraction of the whole circle the shaded region is, and apply that to the total circumference to find the length of the arc.
1. area of whole circle = 17^2*3.14 = 907.46in^2
2. 529.35/907.46 = 0.5833314967
3. circumference of whole circle = 2*3.14*17 = 106.76
4. length of arc = 106.76*0.5833314967 = 62.2764705877 --> 62.28
Answer: a) 453 b) 1537
Step-by-step explanation:
As per given , we have
Margin of error : E= 0.025
Critical value for 95% confidence interval :
a) The prior estimate of population proportion : p=0.08
Required sample size :-
The minimum sample size is 453 U.S. adults.
b) Since the prior estimate of population proportion is not available , so we take p= 0.5
Required sample size :-
The minimum sample size is 1537 U.S. adults.
