amid [387]

Answer:

(38.1,88.6)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 38.3

Sample size, n = 695

Alpha, α = 0.05

Population standard deviation, σ = 3.6

95% Confidence interval:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

$38.3 \pm 1.96(\frac{3.6}{\sqrt{695}} ) = 38.3 \pm 0.267 = (38.033,38.567) \approx (38.1,88.6)$

sleet_krkn [62]

1dollar = 0.7306euros

thus $3,500 dollars can be found by a rule of three

dollar euro

1 ⇒ 0.7306

3500 ⇒ x

we find x as follows:

$x=\frac{0.7306*3500}{1} = 2,557.1$ euros

She will pay 2,557.1 euros per year.

Dividing between the 12 months of the year:

$\frac{2,557.1}{12}=213.1$

Rounding to the nearest whole euro she will pay 213 euros per month.
