Explanation / Answer

1)a)option B; fail to reject Ho because the p value is greater than alpha

b)option B is correct; tere is not sufficient evidence to warrant rejection.........

2)

a) P(X>218.90)=P(Z>(218.9-205.5)/7.8)=P(Z>1.72)=0.0427

b)P(Xbar>204)=P(Z>(204-205.5)/(7.8/sqrt(20))=P(Z>-0.86)=0.8051

c)

option A
