According to the 2019 census, approximately 20.81% of the Canadian population are immigrants. You survey 26 individuals living in Canada and ask each person if they are an immigrant or not. Please use this information to answer the following questions. a. How many of the people surveyed can we expect to be immigrants? Answer: people. Round to at least FOUR digits after the decimal if necessary. b. What is the standard deviation of the number of people surveyed who are immigrants? Answer: people. Round to at least FOUR digits after the decimal if necessary. c. Suppose you know that more than 3 of the people surveyed are immigrants. What is the probability that exactly 9 of the people surveyed are immigrants? Answer: Round to at least FOUR digits after the decimal if necessary. d. What is the probability that the 14th person surveyed is the third person to indicate that they are an immigrant? Answer: Do NOT round your answer; give all the decimals that R prints.
