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.

that the population of all patients who received the recommendation to change their diet is
not equally likely to lower their cholesterol as the population of patients who are prescribed
meds.
O The results are statistically insignificant at a = 0.05, so we can conclude that the success rate
for all patients who receive the recommendation to change their diet is equal to the success
rate for all patients who are prescribed meds.
O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude
that the success rate for the 567 patients who received the recommendation to change their
diet is different from the success rate for the 703 patients who were prescribed meds.
O The results are statistically insignificant at a = 0.05, so there is insufficient evidence to
conclude that the population of all patients who received the recommendation to change their
diet is not equally likely to lower their cholesterol as the population of patients who are
prescribed meds.
g. Interpret the p-value in the context of the study.
O There is a 46.68% chance of a Type I error.
O There is a 46.68% chance that the difference in the success rate for all patients who receive
the change of diet recommendation and all patients who are prescribed meds is at least 2%.
O f the success rate for the sample of patients who receive the recommendation to change their
diet is the same as the success rate for the sample of patients who were prescribed meds and
if another 567 patients are given the recommendation to change their diet and 703 patients are
* prescribed meds then there would be a 46.68% chance of concluding that the difference in the
success rate for all patients who receive the recommendation to change their diet and all
patients who are prescribed meds is at least 2%.
O If the success rate for the population of patients who receive the recommendation to change
their diet is the same as the success rate for the population of patients who are prescribed
meds and if another 567 patients who are given the recommendation to change their diet and
703 patients who are prescribed meds are surveyed then there would be a 46.68% chance that
the percent of the surveyed diet changers who lowered their cholesterol would differ at least
2% compared to the percent of the surveyed med takers who lowered their cholesterol.
h. Interpret the level of significance in the context of the study.
Olf the success rate for the population of patients who receive the recommendation to change
their diet is the same as the success rate for the population of patients who are prescribed
meds and if another 567 patients who are given the recommendation to change their diet and
703 patients who are prescribed meds are surveyed then there would be a 5% chance that we
would end up falsely concuding that the proportion of the 567 patients who received the diet
change recommendation who lowered their cholesterol is different from the proportion of the
703 patients who were prescribed meds who lowered their cholesterol.
O There is a 5% chance that a patient won't be able to afford the meds, so they might as well
change their diet.
O f the success rate for the population of patients who receive the recommendation to change
their diet is the same as the success rate for the population of patients who are prescribed
meds and if another 567 patients who are given the recommendation to change their diet and
703 patients who are prescribed meds are surveyed then there would be a 5% chance that we
would end up falsely concuding that the success rate for the population of patients who
receive the recommendation to change their diet is different from the success rate for the
population of patients who are prescribed meds.
