An investigator anticipates that the proportion of red blossoms in his hybrid plants is 0.15. He intends to take a random sample sample of 50 of his plants. The standard deviation of the sampling distribution of the sample proportion is approximately:

• 0.0505

• 0.0591

• 0.15

• 0.0026

• 0.0034

Which formula do you use to find the standard deviation of a proportion?

•  $\sigma$  

•  $\frac{\sigma}{\sqrt{n}}$  

•  $\mu$  

•  $\sqrt{\frac{p\left(1-p\right)}{n}}$  

What does this formula do?

• Calculates Standard Deviation for Sampling Dist. of Sample Means

• Checks if the samples are independent

• Checks Normality

• Calculates Standard Deviation for Sampling Dist. of Sample Proportions
