Answer:
158.993
Step-by-step explanation:
We have to find the standard deviation of the sampling distribution of the means.
We are given that population standard deviation=σ=2248.5 and sample size=n=200.
Standard deviation of sampling distribution of means=σxbar=σ/√n
σxbar=2248.5/√200
σxbar=2248.5/14.1421
σxbar=158.993
Thus, the standard deviation of the sampling distribution of the means is $158.993.

Answer:
Step-by-step explanation:
Parallel ⇒ So the slopes will definitely be equal
So,
Slope = m = 5
Now,
Point = (x,y) = (4,5)
So, x = 4, y = 5
Putting these in the slope intercept form to get b
5 = (5)(4) + b
5 = 20 + b
b = -20+5
b = -15
So, Putting m and b in the slope intercept form to get the required equation,
Answer:
Step-by-step explanation:
There are lots of ways we can think about the typical number of cavities.
The most patients had 0cavities.
If we split the cavities evenly, each patient would have 2 or 3 cavities.
If we put our dot plot on a balance scale, it would balance when the pivot was between 2 and 3 cavities.
The scale would tip if, for example, we put the pivot at 5 cavities.
There are 8 patients with 2 cavities each. About half of the rest of the patients have fewer than 2 cavities and about half have more than 2 cavities.
Of the choices, it is reasonable to say that a patient typically had about 2 cavities.

The 'typical' number of cavities one patient had can be determined by finding the mode (most common number) in the data set, which should be represented in the dot plot. To do this, one would count the number of dots at each value on the dot plot. The value with the most dots would be the 'typical' number of cavities.
The question is asking for a 'typical' number of cavities one patient had out of Dr. Vance's 63 patients. In statistics, a typical, or 'common', value can be shown by calculating the mode, which is the number that appears most frequently in a data set.
Unfortunately, the dot plot is missing from the information provided. However, to find the mode (or typical value) using a dot plot, you would typically count how many dots are at each value on the plot. The value with the most dots (indicating the most patients with that number of cavities) is the mode. This would be the 'typical' number of cavities a patient of Dr. Vance had last month.
Let's create a hypothetical scenario. If your dot plot looked like this:
The mode would be 2 cavities because 24 patients had this amount, more than any other amount. Therefore, the 'typical' number of cavities one patient had would be 2.
