Step-by-step explanation:
We will have to solve this question using step by step procedure
So let's solve
(21/7+316)(5/2+4-13)
(21/7+316)
Lcm is 7
21+2212/7
2233/7
(5/2+4-13)
Lcm is 2.
5+8-26/2
13-26/2
-13/2
Back to the question
(2233/7)(-13/2)
-29029/14
-2073.5
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)
Answer:
D
Step-by-step explanation:
1+x=3
x=2
x-4=-2
x=2
1+x=-2
x=-3
x+3=5
x=2
x-5=3
x=8
So 1+x=3,x-4=-2,x+3=5 are equivalent
