First, we know it can't be median because 72 is not a value in the data. If you find the mean/average, you will find that it is 72

Answer:

The measure of center is the average or mean.

Step-by-step explanation:

The weights (in pounds) of six dogs are listed below.

17 56 85 38 138 98

Arranging in ascending order, we get

17 38 56 85 98 138

The measure of center is found to be 72 lb.

This is the average or mean. We can check this as:

$\frac{17+38+56+85+98+138}{6} =72$

Suppose that distribution of the daily calcium intake of Americans is left skewed with a mean of 800 mg and a standard deviation

babymother [125]

Answer:

Explained below.

Step-by-step explanation:

According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normal.

Then, the mean of the sampling distribution of sample means is given by,

$\mu_{\bar x}=\mu$

And the standard deviation of the sampling distribution of sample means is given by,

$\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}$

So, if the sample of daily calcium intake of Americans collected is more than 30, then the sampling distribution of $\bar X$ will be approximately normal.

Miller's Steakhouse offers 8 side dishes, 5 types of steak, and 4 toppings. How many different smothered steak dinners can be ma

horrorfan [7]

Answer:

1120

Step-by-step explanation:

To find the possible number of steak dinners, you would multiply the number of choices for each part of the dinner. You would used combinations instead of permutations since the order of the toppings chosen or side dishes chosen do not matter. There are 5 choose 1 choices for types of steak, which is just 5. There are 8 choose 3 choices for side dishes, which is 56. There are 4 choose 3 choices for toppings, which is 4. 5*56*4 is 1120, so there are 1120 possible steak dinners.
