Question

Can you use a distribution, at you are asking high school students their favorite brand of kicks is ? scenario: The failure rate for taking the car exam in central city in 35%. If 250 people take the bar exam, what is the meat. Variance, and standard deviation for the number of failures? N = ___ p = ___ q = ___ 13. Sigma = ___ 14. Sigma^2 = ___ 15. Sigma = ___ In a complete sentence, explain why X or (r) are not used to find the mean, variance, or standard deviation of the binomial probability in #13.

Explanation / Answer

n=250
p = 0.35
q = 0.65
Mean ( np ) =250 * 0.35 = 87.5
Standard Deviation ( npq )= 250*0.35*0.65 = 7.5416
Variance = ( npq )= 250*0.35*0.65 = 56.875
