In a clinical trial of a drug tested to verify its use in helping people to stop smoking, 793 people were treated with 1 mg of this drug. In this group, 26 people reported feeling nauseous. In another control group, which did not receive this drug, the probability that a person in this group reported nausea was 0.0109. a) which probability distribution best describes the number of people who reported feeling sick in this study? b) consider the hypothetical case in which this drug did not contribute in any way to the increase/decrease of reports of nausea. In this case, find the expected value and the standard deviation of the number of people who should report the nausea symptom in this group of 793 people c)do you think the number of people who reported feeling nauseous in this group is compatible with that which would be expected, if the drug had no influence on this side effect, based on the previous item's response? Would you say that we could classify nausea as a side effect of using the drug in question?
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.
