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 t

Helga [31]

Answer:

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:

$\sigma = \sqrt{\frac{p(1-p)}{n}}$

Substitute figures in the equation:

$\sigma = \sqrt{\frac{0.1(1 - 0.1)}{115}}$

$\sigma = \sqrt{\frac{0.1 * 0.9}{115}}$

$\sigma = \sqrt{\frac{0.09}{115}}$

$\sigma = \sqrt{7.826*10^-^4}$

$\sigma = 0.028$

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