Answer:
99% confidence interval is:
(0.00278 < P1 - P2< 0.15921)
Step-by-step explanation:
For calculating a confidence intervale for the difference between the proportions of workers in the two cities, we calculate the following:
Where : proportion sample of individuals who worked
at more than one job in the city one
: Number of respondents in the city one
: proportion sample of individuals who worked
at more than one job in the city two
: Number of respondents in the city two
Then
α = 0.01 and α/2 = 0.005
and
and
The confidence interval is:
(0.00278 < P1 - P2< 0.15921)
Divide by the coefficient of x.
x = 27/47
Answer:
I believe it would be A bc
Step-by-step explanation:
A= 42
B= 32
C= 20
D= 36
Answer:
30 is the perimeter i think 2 x 5 = 10 + 2 x 4.5 = 10 x 2 = 20 so 20 + 10 = 30
I think the area is 45, 5 x 4.5 = 22.5 and 2 x 22.5 = 45
