Ashipment of beach balls with a mean diameter of 28 cm and a standard deviation of 1.3 cm is normally distributed. by how many standard deviations does a beach ball with a diameter of 26.7 cm differ from the mean?
a. 1
b. 1.3
c. 2
d. 3

a. 1

Step-by-step explanation:

Given : Population mean :

Standard deviation :

Let n be the number of times  a beach ball with a diameter of 26.7 cm differ from the mean.

Then, we have

Hence, a beach ball with a diameter of 26.7 cm is 1 standard deviation differ from the mean.

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
