A survey оf 1731 rаndоmly selected Cаlifоrniа drivers showed that 532 of them had received a parking ticket in the last five years. Construct the 95% confidence interval for the proportion of California drivers that had received a parking ticket in the last 5 years. a. What is the point estimate of the proportion of California Drivers who have received a parking ticket in the last 5 years? Round to three decimal places. [answera] b. Does the sample meet the conditions to calculate the confidence interval for the proportion? [answerb] because the sample is random, the sample is less than 5% of the population and [answerc]. c. Use the appropriate formula to find the margin of error, rounded to three decimal places. Remember to round off only at the end. [answerd] d. Using the point estimate and the margin of error from part c, find the 95% confidence interval for the proportion of California drivers who have received a parking ticket in the last five years. Round to three decimal places. [answere]
