In a certain normal distribution of scores, the mean is 50 and the standard deviation is 6. find the z-score corresponding to a score of 60.

z-score = 1.667

Step-by-step explanation:

The provided information are:

Population mean = 50

Population standard deviation = 6

Score (X) = 60

The formula to calculate the z-score is:

The z- score can be calculated as:

Hence, the z-score is 1.667.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
