77julia77 [94]

Answer: (14.18, 15.08)

Step-by-step explanation:

Given : Sample size : n= 64

Sample mean : $\overline{x}=15$

Standard deviation : $\sigma=4$

Significance level : $\alpha: 1-0.90=0.1$

Critical value : $z_{\alpha/2}=1.645$

The confidence interval for population mean is given by :-

$\overline{x}\pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=15\pm(1.645)\dfrac{4}{\sqrt{64}}\\\\\approx15\pm0.82\\\\=(14.18,\ 15.08)$

Hence, the 90% confidence interval for the population mean of waiting times is (14.18, 15.08).

If f(x)=x^2+2x-4 and g(x)=3x+1 find f(g(x))=__x^2+__x+__

Korvikt [17]

Step-by-step explanation:

f(x) = x² + 2x - 4

g(x) = 3x + 1

f(g(x)) = f(3x + 1)

f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4

= 9x² + 6x + 1 + 6x + 2 - 4

= 9x² + 12x -1
