Answer:

25,132.74 miles

Step-by-step explanation:

Hello!

We are basically asked to find the circumference of the Earth's cross-section.

Circumference: $C = 2\pi r$

We can replace 2r with the diameter, because the diameter is 2 times the radius.

Multiply the Diameter by pi:

$C = \pi D$
$C = 8000\pi$
$C = 25,132.7412287183 \approx 25,132.74$

It is around 25,132.74 miles around.

3. Suppose you are testing H0 : µ = 20 vs H1 : µ > 20. The sample is large (n = 71) and the variance, σ 2 , is known. (a) Fin

LUCKY_DIMON [66]

Answer:

We reject the null hypothesis.

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 71

Population variance is known.

Level of significance, α = 0.08

$z_{\text{stat}} = 1.56$

The null and alternate hypothesis are:

$H_{0}: \mu = 20\\H_A: \mu > 20$

We use one-tailed z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} } = 1.56$

Now, $z_{critical} \text{ at 0.08 level of significance } = 1.41$

Since,

$z_{stat} > z_{critical}$

We fail to accept the null hypothesis and reject it and accept the alternate hypothesis.
