p=0.63 and n=80 p(x>48)

Solutions

Expert Solution

Solution :

Given that,

p = 0.63

q = 1 - p = 1 - 0.63 = 0.37

n = 80

Using binomial distribution,

= n * p = 80 * 0.63 = 50.4

= n * p * q = 80 * 0.63 * 0.37 = 4.32

Using continuity correction ,

P(x > 48) = 1 - P(x < 48 )

= 1 - P((x - ) / < (48 - 50.4) / 4.32)

= 1 - P(z < -0.56 )

= 1 - 0.2877

= 0.7123
