Explanation / Answer

Since you have multiple questions,so i am attaching answers for #9 and #10

9)

n=4

=8

=40

standard error =/n

                        =8/4

                        =8/2

                        =4

10)

=100

=15

n=9

x=97

z=(x-)/(/n)

=(97-100)/(15/9)

=(-3)/(5)

=-0.6

P(x>97) =P(z>-0.6)

            =1-P(z<-0.6)

            =1-0.2743

            =0.7257
