Select the correct answer The numbers of pages in the books in a library follow a normal distribution. If the mean number of pages is 180 and the standard deviation is 30 pages, what can you conclude?
А. About 60% of the books have fewer than 150 pages.
BAbout 16% of the books have fewer than 150 pages.
C. About 95% of the books have more than 150 pages.
DAbout 16% of the books have more than 150 pages

Solution given;

mean=180

standard deviation=30

now

percentage =standard deviation/mean ×100%

=30/180×100%

=16%

soBAbout 16% of the books have fewer than 150 pages.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
