Suppose 9% of students are veterans and 133 students are involved in sports. How unusual would it be to have no more than 6 veterans involved in sports? (6 veterans is about 4.5113%) When working with samples of size 133, what is the mean of the sampling distribution for the proportion of veterans? When working with samples of size 133, what is the standard error of the sampling distribution for the proportion of veterans? Compute P(ˆp≤p^≤ 0.045113). P(ˆp≤p^≤ 0.045113) = NOTE: Give results accurate to 5 decimal places Is this result unusual? Yes, there is a less than 50% chance of this happening by random variation. No, there is at least a 50% chance of this happening by random variation.
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.
