People who work out vigorously for an hour or more experience loss of electrolytes such as calcium, potassium, and sodium that are released from the body by sweat. Potassium is a very important part of many bodily functions for athletes, including transmitting nerve signals and fluid balance. A random sample of 9 athletes were given water after a vigorous one-hour workout and their electrolytes were then checked and recorded. After another vigorous one-hour workout on a different day, the same 9 athletes’ electrolytes were checked after being given a sports drink. Their potassium levels are given below. Do sports drinks help replenish lost potassium levels more than water after a vigorous workout? Refer to the table below. Water: 4.17, 2.88, 4.71, 4.79, 5.11, 4.12, 3.95, 4.22, 3.86 Sports Drink: 4.20, 3.30, 4.69, 4.82, 5.17, 4.08, 4.49, 4.54,3.71 hypothesis test needed Hypothesis test needed
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.
