Binomial Distribution on Use technology (calculator, Microsolt Excel, or Google Sheets) to find the following binomial probabilities. Round to the nearest thousandth. According to the Center for Disease Control, 15% of US adults are estimated to have chronic kidney disease. A random sample of 150 US adults are selected. What is the probability that 1. Exactly 35 have chronic kidney disease? RE ,135)= 2 No more than 15 have chronic kidney disease? 3 Thirty or more have chronic kidney disease? Next pag 9:45 PM ^40 12/2/2017

Explanation / Answer

Solution:- p = 0.15 , n = 150

a) P(r = 35) = 0.0021

b) P(r <= 15) = 0.0493

c) P(r <= 30) = 0.9622

formula binomial distribution: ncr*pr*q(n-r)
