2. Nonrandom Sampling Procedure:
_   Leave Clint's dorm room and ask the first T individuals encountered if he/she
 supports Clint and record the answer (T equals the sample size).
_   Calculate the fraction of the sample supporting Clint.


`
The Nonrandom Sample box is checked; hence, the nonrandom sampling procedure will
 be used. As in exercise 1, the sample size equals 16, the actual fraction 
 supporting Clint, ActFrac, equals .5, and the From-To values are specified
 as .45 and .55. Click the Start button and then after many, many, repetitions
 click Stop.

`
2a. What does the mean of the estimates equal?
_
2b. What is the magnitude of the bias?
_
2c. What does the variance of the estimates equal?
_
2d. What percent of the repetitions fall within .05 of the actual fraction, ActFrac?
