In a recent poll, a random sample of adults in some country (18 years and older) was asked, "When you see an ad emphasizing that a product is "Made in our coum are you more likely to buy it, less likely to buy it, or neither more nor less likely to buy it?" The results of the survey, by age group, are presented in the following contingency table. Complete parts (a) through (c). Purchase likelihood 18-34 35-44 45-54 55+ Total More likely Less likely Neither more nor less likely 290 211 230 312 360 400 1302 28 9. 30 17 84 173 122 796 Total 548 532 563 539 2182 (a) What is the probability that a randomly selected individual is 35 to 44 years of age, given the individual is more likely to buy a product emphasized as "Made in c country"? The probability is approximately (Round to three decimal places as needed.) (b) What is the probability that a randomly selected individual is more likely to buy a product emphasized as "Made in our country," given the individual is 35 to 44 ye of age?

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
