You are conducting a survey at a college with 800 students, 50 faculty and 150 administrators. Each of these 1,000 persons has a single listing in the phone directory. Suppose you were to cut up the directory and pull out one listing at random, what is the probability it would (a.) be a student (b.) a faculty member (c.) an administrator (d.) a faculty or administrator (e.) anyone besides administrator (f.) explain each answer...
BEST GETS 10 POINTS!
Random sampling and probability?
a) 800/100 =.8
b) 50/1000 =.05
c) 150/1000 =.15
d) .05+.15=.2
