A shipment 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

Answers

Answer: a. 1

Step-by-step explanation:

Given : Population mean :\mu=28\ cm

Standard deviation : \sigma=1.3\ cm

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

Then, we have

28-n(1.3)=26.7\n\n\Rightarrow\ 1.3n=28-26.7\n\n\Rightarrow\ 1.3 n=1.3\n\n\Rightarrow\ n=1

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