Hannah claims that people who live in southern states spend 9 hours more per week outside than do people in northern states. She

selects a random sample from each group. The mean number of hours per week that people in southern states spent outside is 18.6, and the mean number of hours per week that people in northern states spent outside is 14.4. A 99 percent confidence interval to estimate the difference in population means (southern minus northern) is (0.4,8.0).

Plz help!!
AlexFokin [52]

Answer: 50 Books

Step-by-step explanation:

B = number of books in Ruben's collection BEFORE he bought new ones.

So  6 books were bought which increased his collection by 12%.

12% as a decimal would be 0.12..then we add the variable which represents the number of books, 0.12B.

So then we know 0.12=6

*We need to isolate the variable* So we would divide 0.12 on both sides. 0.12/0.12 and 0.12/6 which is 50.

Hope this helps! :)
