A college would like to estimate the proportion of its students that work full-time while going to school. A researcher at the college found that 162 students out of a random sample of 439 students worked full-time while going to school. Determine the point estimate, p and the sample standard deviation, 85. Round the sample proportion to four decimal places and round the standard deviation to six decimal places, if necessary. Using a 98% confidence level, determine the margin of error, E, and a confidence interval for the proportion of all students at the college who work full-time while going to school. Report the confidence interval using interval notation. Round solutions to four decimal places, if necessary. The margin of error is given by E A 98% confidence interval is given by Question Help: DVideo
