Answer:
Since both and , you can use a normal distribution to approximate the binomial distribution.
The mean is of 11.1 and the standard deviation is of 2.64.
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
Using the normal distribution to approximate the binomial distribution.
This is possible if:
A survey of U.S. adults found that 37% have been to court. You randomly select 30 U.S.
This means that
Test if it is possible:
Since both and , you can use a normal distribution to approximate the binomial distribution.
