In a test of the effectiveness of garlic for lowering cholesterol, 48 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before-after) in their levels of LDL cholesterol (in mg/dL) have a mean of 5.8 and a standard deviation of 19.4. Construct a 99% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment Click here to view at distribution table Click here to view page 1 of the standard normal distribution table Click here to view page 2 of the standard normal distribution table What Is the confidence interval estimate of the population mean u? O mg/dl.

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.
