The given statement about normal score that it is expected z score of a data value is true.

Given A statement that a normal z score is the expected z score of a data value, assuming the distribution of the random variable is normal.

We have to tell whether the given statement is true or false.

In z test the z score or standard score is the number of standard deviations by which the value of a raw score is above or below the mean value of what is observed or measured.

A normal distribution is arrangement of a data set in which most values cluster in the middle of the range and the rest taper off symmetrically toward either extreme.

A random variable is a variable which is identified without following any criteria.

A Z test is any statistical test for which the distribution of the test statistic under the null hypothesis ca be approximated by a normal distribution.

Hence the given statement about normal score is absolutely true.

Determine of which lines, if any, are parallel or perpendicular. Explain.
nalin [4]

Answer:

lines b and c are perpendicular

Step-by-step explanation:

Use slope

slope for parallel is the same

slope for perpendicular is negative reciprocal

line a slope- 1-3/-2-0 is -2/-2 or 1

line b slope- 1-4/4-6 is -3/-2 or 3/2

line c slope- 3-1/1-4 is 2/-3 or - 2/3

none are the same so none are parallel

- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular
