Explanation / Answer
tota prob=
0.0014+0.0194+0.1049+0.2836+0.3834+0.2073
mean=mu=xP(X)
=0*0.0014+1*0.0194+2*0.1049+3*0.2836+4*0.3834+5*0.2073
=3.65
=3.7(ONE DECIMAL)
MEAN=3.7
sOLUTIONB
var=x2 P(X=x)-mean2
=0^2*0.0014+1^2*0.0194+2^2*0.1049+3^2*0.2836+4^2*0.3834+5^2*0.2073-(3.7)2
variance=0.6183
sd=sqrt(0.6183)
=0.7863
=0.79
answer standard deviation=0.8(to one decimal)
