Given a mean of 7.6 and a standard deviation of 3.1, within how many standard deviations of the mean do the values 10, 9, 11, 5, and 3 fall?

The z-score value of the data is -0.838.

Step-by-step explanation:

Given : A mean of 7.6 and a standard deviation of 3.1.

To find : How many standard deviations of the mean do the values 10, 9, 11, 5, and 3 fall?

Solution :

Mean

Standard deviation

Values 10, 9, 11, 5, and 3 i.e. x=5

The z-score value for x=5 is given by

The z-score value of the data is -0.838.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
