For a sample size of 115 and a population parameter of 0.1,what is the standard deviation of the normal curve that can be used to approximate the binomial probability histogram. Round your answer to three decimal places A.0.028

B.0.054

C.0.043

D.0.035

A) 0.028

Step-by-step explanation:

Given:

Sample size, n = 115

Population parameter, p = 0.1

The X-Bin(n=155, p=0.1)

Required:

Find the standard deviation of the normal curve that can be used to approximate the binomial probability histogram.

To find the standard deviation, use the formula below:

Substitute figures in the equation:

The Standard deviation of the normal curve that can be used to approximate the binomial probability histogram is 0.028

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
