Question

A study states that 34% of people prefer their eggs crambled. you randomly select 7 people who had egs for breakfast. what is the standard deviation for this distributions

Answer 1

Mean of the binomial distribution μ = 2.38

Standard deviation of the binomial distribution σ = 1.2533

Explanation:

Explanation:-

Given Population proportion

p = 34 % = 0.34

q = 1- p

= 1 -0.34

= 0.66

q = 0.66

Mean of the binomial distribution

μ = n p = 2.38

Standard deviation of the binomial distribution

σ = √n p q = 1.2533
