Answer 1

The answer is:

${\color{DarkRed} \text{ A. P(At least 4) = 0.952}}$

The population proportion of success is p=0.5, and the sample size is n = 13. We need to compute Pr(X > 4): The population mean is computed as: =n.p= 13.0.5 = 6.5 and the population standard deviation is computed as: o= Vn.p.(1 – p) = V13.0.5 . (1 – 0.5) = 1.8028 Therefore, we get that Pr(X Binomial > 4) Pr(X Normal > 3.5) Pr(2> XX1.190286-5) = P1( 22 1.5025 ) = Pr(Z > -1.6641) = 1 -0.048 = 0.952
