Binomial Distribution

Answer 1

Hi   Natalie...Ill take a crack at this one....

 

     n=16

    

      p= 0.52

 

     q= (1-p)

 

 

         Mean= (n) (p)

 

 

          Mean= (16)  (0.52)   =  8.32

 

 

         SDIEV  = Sqrt ((n) (p) (q))       

 

 

           SDIEV = SQRT((16) (0.52) (0.48))

 

 

           SDIEV  = 1.998

 

                                           ------6.332----------8.32--------10.318

                                                   (-)                  (mean)         (+)
