Pryme Tyme Soda Werks would like to dominate the college energy drink market. They’ve taken their leading energy drink, Shoker, and added a proprietary blend of nootropic supplements (i.e., vitamins and minerals that are supposed to increase cognitive processing, such as choline and gingko biloba). Their big marketing angle is that Roket Phule not only increases your energy, but makes you smarter too! We know that the population parameters for IQ is (μ = 100, σ = 15). You randomly select 40 students and give them all the Roket Phule they can drink for a month. At the end of that time, you give them an IQ Test and find a mean IQ . Give at least 1 alternative explanation, other than effect of the nootropics, that drinker’s IQ may have been higher?
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.
