Question

Say we have a random sample of n = 15 people who visit a library’s website to browse their catalogue. With p = 0.1 of the population proportion who reserve a book while browsing, what is the probability of selecting exactly 14 users who actually make a reservation in the random sample? Please round to the fourth decimal place.

soli 0 Givent If we have a random Sample of n-2 M = 15 people who visits library website, such that, with, P=0.1, of population, we need to find at exactly 14 users actually make reservation, Since, it follows Binomial distribution, P(X=x) * (0) * * (0) we have 7:15, P=0.1, q=t-p q=1-001 q=0.9, we need to find at X= 14 15-14 P(x=14) = (15(19) * (0-1)'**(0.97% * (0.1) "* 10.9) Пся 15414) .: Plx=14) = 1.35*102 -> (15) *0.9 *[0.194 13.5 *(0,134 =(1-35 -13 35 * 10
