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
