The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 247.3 and a standard deviation of 65.3. (All units are 1000 cells/ul) Using the empirical rule, find each approximate percentage below a. What is the approximate percentage of women with platelet counts within 2 standard deviations of the mean, or between 116.7 and 377.9? b. What is the approximate percentage of women with platelet counts between 51.4 and 443.2? a. Approximately % of women in this group have platelet counts within 2 standard deviations of the mean, or between 116.7 and 377.9 (Type an integer or a decimal. Do not round) b. Approximately % of women in this group have platelet counts between 51.4 and 443.2 (Type an integer or a decimal. Do not round.)

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.
