A supplier sells 2 and 1/4 pounds of mulch for every 1 and 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and grav

polet [3.4K]

Because ratios can be written as fractions
$\frac{mulch}{2.25}=\frac{gravel}{1.33}$

172 = $\frac{mulch}{2.25}+ \frac{gravel}{1.33}$
172 - $\frac{mulch}{2.25}$ = $\frac{gravel}{1.33}$
76.44 mulch = x amount of gravel = 172
Gravel = 172 - 76.44
= 95.56

Goofy's fast food center wishes to estimate the proportion of people in its city that will purchase its products. Suppose the tr

Setler79 [48]

Answer:

$\mu_{\hat p}= 0.06$

$\sigma_{\hat p}= \sqrt{\frac{0.06*(1-0.06)}{280}}= 0.0142$

And we want to find this probability:

$p(\hat p$

$z = \frac{p \mu_{\hat p}}{\sigma_{\hat p}}$

$z = \frac{0.09-0.06}{0.0142}= 2.114$

And we can find this probability:

$P(z$

And using the normal table or excel we got:

$P(z$

Step-by-step explanation:

For this case we have the following info given:

$n = 280$ represent the sample size

$p =0.06$ represent the true proportion

The sample proportion can be approximated with this distribution:

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

The mean is given by:

$\mu_{\hat p}= 0.06$

And the deviation is given by:

$\sigma_{\hat p}= \sqrt{\frac{0.06*(1-0.06)}{280}}= 0.0142$

And we want to find this probability:

$p(\hat p$

And we can use the z score formula given by:

$z = \frac{p \mu_{\hat p}}{\sigma_{\hat p}}$

And replacing we got:

$z = \frac{0.09-0.06}{0.0142}= 2.114$

And we can find this probability:

$P(z$

And using the normal table or excel we got:

$P(z$
