Each respondent was given a score, from 1 to 15, on his or her knowledge of the COFLU-20. A score from 1 to 7 was considered to indicate poor' knowledge, 8 to 11 indicated 'satisfactory knowledge and 12 to 15 indicated good knowledge. Table 2 below shows the knowledge level of respondents, by age group. Table 2 Age Group Knowledge Level Total Poor Satisfactory Good 18 - 25 33 16 13 62 26 - 34 30 18 | 12 | 60 35 - 44 29 14 12 55 45 - 54 36 16 18 70 55 - 75 17 14 22 53 Total 145 78 77 300 (c) Using Table 2, assist the researcher to calculate the probability that a randomly selected respondent: @) is below 35 years of age and has good knowledge of the COFLU-20 (i) is below 35 years of age or has good knowledge of the COFLU-20 91

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.
