In the same study discussed in Question 3, the participants were also asked if they owned a car. The researchers found that 79% of the participants own a car. Suppose 83% of all Canadians own a car. a. Determine the parameter, estimator, and estimate. b. Can we determine the exact distribution of the estimator in this setting? If not, what is the approximate distribution? c. Based on vour findings in part b, what is the probability that the estimate is greater than 75%? d. Based on your findings in part b, what is the probability that the estimate is between 80% and 90%? e. What sample size would be needed if the researchers want the standard deviation of the estimator to be less than or equal to 0.01?
