Suppose x has a normal distribution with mean μ = 45 and standard deviation σ = 9. describe the distribution of x values for sam

Fofino [41]

The standard deviation of a particular sample is equal to the standard deviation divided by the square root of the sample size. That is, $\sigma_x=\frac{\sigma}{\sqrt n}$
The mean of a particular sample is equal to the mean of the set the sample was taken from. That is,
$\mu_x=\mu$
$\text{In your case, }\sigma_x=\frac{9}{\sqrt4}=\frac92\text{ and }\mu_x=45.$

No. of diners = 240

Musya8 [376]

Answer:

<u>We need to buy 3 cases of juice.</u>

Correct statement and question:

No. of diners = 240 Portions of juice served = 4 oz. per diner Size of juice can = 48 oz. How many cases of juice required if there are 8 cans in a case and you must buy a whole case?

Source:

Previous question that you can search at brainly

Step-by-step explanation:

Let's calculate the number of cases of juice are required this way:

Number of cases required = [(Number of dinners * portion of juice served)/Size of juice can]/Cans in a case

Replacing with the real values, we have:

Number of cases required = [(240 * 4)/48]/8

Number of cases required = [(960)/48]/8

Number of cases required = 20/8

Number of cases required = 2.5

<u>But let's remember that we must buy only whole cases, then we need to buy 3 cases of juice.</u>
