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 42 students out of a random sample of 389 students worked full-time while going to school. Determine the point estimate, ˆp and the sample standard deviation, Sˆp^. Round the sample proportion to four decimal places and round the standard deviation to six decimal places, if necessary. ˆp= Sˆp^= Using a 99% 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 99% confidence interval is given by
