Hypertension is a common chronic disease among overweighed people. From a survey, 34.6% people who are overweighed are suffering from hypertension, in Macau. If a random sample of 200 people in Macau who are overweighed was selected, find the probability that who get hypertension is, a. exactly 75 in the sample. b. at most 60 of those in the sample. c. between 70 and 120, inclusive.

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.
