Explanation / Answer

Solution:

Given, p = Probability of success = 0.45

n = sample size = 100

Here x: Number of women's say that flexible work

Here distribution of x is binomial distribution.

(a) P( X < 52 ) = .............? ( 52% means 52 out of 100 )

Using excel , =BINOMDIST(52,100,0.45,TRUE)

P( X < 52 ) = 0.9338

(b) P( 41 < x < 52 ) = ---------------?

Using excel , =BINOMDIST(52,100,0.45,TRUE)-BINOMDIST(41,100,0.45,TRUE)

P( 41 < x < 52 ) = 0.6923
