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?

The margin of error is multiplied by 0.5.
The margin of error is multiplied by 2

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!

the correct answer is the last option
