A sample tested the claim that heights of men and heights of women have difference variances, with s 7.43793 cm for women and 7.14502 cm for men. The sample sizes are n, = 147 and n2 = 153. When using the F test with these data, is it correct to %3D reason that there is no need to check for normality because n, > 30 and n, > 30? Choose the correct answer below. O A. Yes. The F test has a requirement that samples be from normally distributed populations, but this requirement can be ignored for large samples (n, and n2 greater than 30). O B. No. There is no need to check for normality regardless of the sample size. There is no normality requirement for the F test. OC. No. The F test has a requirement that samples be from normally distributed populations, regardless of how large the samples are. O D. No. There is no need to check for normality as long as n, 2 10 and n2 2 10.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
