Answer:

Step-by-step explanation:

from the question,

the mean 14

the standard deviation is 3

and sample size is 10.

since the n which is the sample size is 10, then the distribution is mound shaped.

why?

this is due to the fact that the random variable from which we took the sample is mound shaped.

The sampling distribution of the mean is normally distributed although the question says the random variable is not normally distributed. so the shape is bell shaped and normally distributed.

the standard deviation of the mean is

3/√10

= 0.948

irina1246 [14]

So the image below shows what quadrants are. From the top-right square, the order of quadrants goes from 1-4 in a counter-clockwise matter.

Quadrant I: Top-right square

Quadrant II: Top-left square

Quadrant III: Bottom-left square

Quadrant IV: Bottom-right square.

Any points that are on the bolded vertical line are on the y-axis, and any points on the bolded horizontal line is on the x-axis.
