All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample to make a

statistical inference about the mean of the normally distributed population from which it was drawn?

ME.

The margin of error is multiplied by /05

The margin of error is multiplied by 12

The margin of error is multiplied by 05,

The margin of error is multiplied by 2.

Save and Exit

The margin of error is multiplied by 1.41, which is 1 divided by the square root of 5.

Step-by-step explanation:

The margin of error is:

In which z is related to the confidence level, is the standard deviation of the population and n is the size of the sample.

The margin of error is inverse proportional to the square root of the sample size.

Then

Sample size n:

Modified(half the sample size):

Ratio

The margin of error is multiplied by 1.41, which is 1 divided by the square root of 5.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
