i believe it could be A. statistics is basically a collection of data, organizations, or an analysis. Im sorry if that is incorrect
Answer:
line a and b are parallel, there is no perpendicular lines
Step-by-step explanation:
Looking at the slope of each line, you can identify whether the lines are parallel, perpendicularlar, or neither.
When the slopes are the same, they are parallel.
When the slopes have opposite sign and numerator and denominator flipped, they are perpendicular. Ex. and are perpendicular slopes.
Finding slope is using the formula:
Line a has slope =
Line b also has slope
Line c has slope 2
Since slope of line a and b are same, they are parallel.
Line c is not perpendicular to line a and b because the slope should have opposite sign and numerator and denominator flipped, which is 4 not 2.

Answer:
<h3>The given statement " The distribution of the sample mean, x-bar, will be normally distributed if the sample is obtained from a population that is normally distributed, regardless of the sample size " is <u>
True. </u></h3>
Step-by-step explanation:
Given statement is " The distribution of the sample mean, x overbar, will be normally distributed if the sample is obtained from a population that is normally distributed, regardless of the sample size".
<h3>To check whether the given statement is true or not :</h3>
- The distribution of the sample mean, x-bar, will be normally distributed if the sample is obtained from a population that is normally distributed, regardless of the sample size is <u>True. </u>
- The standard error of the mean is divided into half, then the sample size must be doubled.
∴ The given statement is true.
