If (1/9x)-2 , what is f–1(x)?

1 answer:

3 0

F(x) = (1/9 x) - 2
y = (1/9 x) - 2
(1/9 x) = y + 2
x = 9(y + 2) = 9y + 18

f^-1(x) = 9x + 18

Answer:

Margin of Error = 1.96 $\times$ 7.75 = 15.19

Step-by-step explanation:

i) Margin of Error of a population with a standard deviation of 7.75?

ii) Let us assume a two tailed test with a 95% confidence interval

iii) $Z_{\frac{\alpha }{2} } = Z_{\frac{\ 0.05 }{2} } = Z_{0.025} = 1.96$

iv) therefore Margin of Error = 1.96 $\times$ 7.75 = 15.19
