Wingspans of adult horses have approximate normal distribution with mean 125 cm and standard deviation 12 cm. What are the rst a
blagie [28]

Answer:

The first and third quartile of the wingspans are 116.9 cm and 133.1 cm respectively.

Step-by-step explanation:

The first and third quartile of a normal distribution are:

Q_{1}=\mu-0.675\sigma\\\\Q_{3}=\mu+0.675\sigma

The information provided is as follows:

\mu=125\\\sigma=12

Compute the first and third quartile of the wingspans as follows:

Q_{1}=\mu-0.675\sigma=125-(0.675\times 12)=116.9\\\\Q_{3}=\mu+0.675\sigma=125+(0.675\times 12)=133.1

Thus, the first and third quartile of the wingspans are 116.9 cm and 133.1 cm respectively.
