Suppose that we will randomly select a sample of 106 measurements from a population having a mean equal to 19 and a standard dev

svet-max [94.6K]

Answer:

$z =\frac{18.45-19}{\frac{7}{\sqrt{106}}}= -0.809$

And if we use the normal standard distribution or excel we got:

$P(z$

Step-by-step explanation:

For this case we have the following info given:

$\mu = 19$ represent the mean

$\sigma = 7$ represent the standard deviation

$n = 106$ represent the sample size

The distribution for the sample size if we use the central limit theorem (n>30) is given by:

$\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})$

And for this case we want to find the following probability:

$P(\bar X< 18.45)$

And for this case we can use the z score formula given by:

$z =\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z =\frac{18.45-19}{\frac{7}{\sqrt{106}}}= -0.809$

And if we use the normal standard distribution or excel we got:

$P(z$

On average, Stan drinks 3/4 of a 8 ounce glass of water in 1/2 of an hour.

sweet [91]

<h3>Stan drinks 12 ounces of water in 1 hour</h3>

<em><u>Solution:</u></em>

Given that,

Stan drinks 3/4 of a 8 ounce glass of water in 1/2 of an hour

Which means,

$\frac{3}{4}\ of\ 8\ ounce = \frac{1}{2}\ hour$

$\frac{3}{4} \times 8 = 0.5\ hour\\$

Therefore,

6 ounces is drank in 0.5 hour

We have to find the water he drinks in an hour

Let "x" be the water he drinks in 1 hour

Thus we get,

6 ounce = 0.5 hour

x ounces = 1 hour

This forms a proportion and we can solve the sum by cross multiplying

$6 \times 1 = 0.5 \times x\\\\0.5x = 6\\\\x = \frac{6}{0.5}\\\\x = 12$

Thus, he drinks 12 ounces of water in 1 hour

Klio2033 [76]

Answer:

He paid 80 at the start, so his starting must have been 80

Step-by-step explanation:

80+40=120...

so either 0, or 80 because he owed nothing, or he owed the 80, then the 40 for medication

I hope this helps!
