Between 7 and 12 (including 7 and 12) of them major in STEM.
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.
33% of all college students major in STEM (Science, Technology, Engineering, and Math). If 39 college students are randomly selected, find the
d. Between 7 and 12 (including 7 and 12) of them major in STEM.
Given,
Number of College Students are selected = n = 39
Probability of successes i.e students major in STEM = p = 0.33
Probability of failure i.e students major not in STEM = q = 0.67
