A. n = 58
rr = 0.60
mean = 58*0.6 = 34.8
Standard deviation = 58∗0.6∗0.4? =13.92?
Standard deviation=3.7310
B. n=96 , rr=0.4
Mean = 96*0.4 =38.4
Standard deviation =96∗0.4∗0.6?
=23.04? =4.8
Standard deviation =4.8
C. n =45 , rr = 0.95
Mean = 45*0.95 = 42.75
Standard deviation =45∗0.95∗0.05? =
2.1375? = 1.4620
Standard deviation = 1.4620
Step-by-step explanation
For a binomial random variable with n,p
mean = np
standard deviation =np(1−p)?
