of the 43 men surveyed, 34 are considered dexterous. As for women, there are 31 of them
they consider leftists. Make a contingency table with the data of the problem and calculate:

a) Probability that by choosing a person at random and being a man.
b) Probability that when choosing a person at random she is a woman and right.

For a school newspaper article, cienna conducted a survey to find out students’ favorite subjects. she polled all the students in mrs. lopez’s advanced dance class. why is her data likely to be skewed? honors dance students are more likely to enjoy dance than students in the general population, so dance may be overrepresented. cienna should have interviewed all the students in the school to get more accurate data. honors dance students are more likely to enjoy dance than students in the general population, so dance will be underrepresented. cienna should have interviewed only every other student in the class to avoid having too many people.

Find the value of the variable and the length of each secant segment.
