X = -30
First combine like terms (0.02x - 0.01x = 0.01x) (-4 - 2 = -6)
0.01x - 6 = -6.3
Then add 6 (-6 + 6 = 0) (-6.3 + 6 = -0.3)
0.01x = -0.3
Then divide by 0.01 to find what x is alone (0.01x ÷ 0.01 = x) (-0.3 ÷ 0.01 = -30)
x=-30
100,000 (sorry if I'm wrong)
Answer:
10000
Step-by-step explanation:
Answer:
The standard error of the sample proportion is closest to 1%
Step-by-step explanation:
Standard error of the sample proportion is given as
σₓ = √[p(1-p)/n]
where
p = sample proportion = estimated to be 23% = 0.23
n = Sample size = 2500
σₓ = √[p(1-p)/n]
σₓ = √[0.23×0.77/2500]
σₓ = 0.0084166502 = 0.00842
σₓ = 0.00842 = 0.842%
Hence, it is easy to see that the standard error of the sample proportion is closest to 1%.
