Answer 2

Cats sleeps more than 17 hours and less than 13 hours a day.

Explanation:

It is given that cats sleep mean of 15 hours and a standard deviation of 2 hours which means cats sleep near about 15 hours daily with a dispersion of 2.

⇒ Cats sleeps = ( 15-2, 15+2) hours daily.

⇒ Cats sleeps more than 17 hours and less than 13 hours a day.

Thus, first option is correct.
