We wish to estimate (with 90% confidence) the proportion of students take the bus to school. We survey a random sample of 650 students and get the following results: 310 students take the bus, 335 students do not take the bus and 5 students did not respond We should use: ZInterval 2-SampZInt 2-PropZInt 1-PropZInt 2-SampTInt TInterval
