Suppose a large shipment of microwave ovens contained 12% defectives. If a sample of size 474 is selected, what is the probabili

melisa1 [442]

Answer:

$P(\hat p>0.14)$

And using the z score given by:

$z = \frac{\hat p -\mu_p}{\sigma_p}$

Where:

$\mu_{\hat p} = 0.12$

$\sigma_{\hat p}= \sqrt{\frac{0.12*(1-0.12)}{474}}= 0.0149$

If we find the z score for $\hat p =0.14$ we got:

$z = \frac{0.14-0.12}{0.0149}= 1.340$

So we want to find this probability:

$P(z>1.340)$

And using the complement rule and the normal standard distribution and excel we got:

$P(Z>1.340) = 1-P(Z$

Step-by-step explanation:

For this case we have the proportion of interest given $p =0.12$ . And we have a sample size selected n = 474

The distribution of $\hat p$ is given by:

$\hat p \sim N (p , \sqrt{\frac{p(1-p)}{n}})$

We want to find this probability:

$P(\hat p>0.14)$

And using the z score given by:

$z = \frac{\hat p -\mu_p}{\sigma_p}$

Where:

$\mu_{\hat p} = 0.12$

$\sigma_{\hat p}= \sqrt{\frac{0.12*(1-0.12)}{474}}= 0.0149$

If we find the z score for $\hat p =0.14$ we got:

$z = \frac{0.14-0.12}{0.0149}= 1.340$

So we want to find this probability:

$P(z>1.340)$

And using the complement rule and the normal standard distribution and excel we got:

$P(Z>1.340) = 1-P(Z$

The volume of a pyramid with a square base where the area of the base is 8.7m^2 and the height is 10

MrMuchimi

Answer:

29 m³

Step-by-step explanation:

The applicable formula is ...

V = (1/3)Bh

Assuming the height is 10 m, the volume is ...

V = (1/3)(8.7 m²)(10 m) = 29 m³

_____

The shape of the base is irrelevant.

Help me solve this questions with steps please

Flauer [41]

Answer:

Step-by-step explanation:

Since the triangle is right use the tangent ratio to find x

tan22° = $\frac{opposite}{adjacent}$ = $\frac{203}{x}$

Multiply both sides by x

x × tan22° = 203 ( divide both sides by tan22° )

x = $\frac{203}{tan22}$ ≈ 502.5 m → B
