<PRE><B>Question 1042156</B>
A study of elephants is conducted to determine the average weight of a certain subspecies of elephants. The standard deviation for the population is 1000 pounds. At a 95% level, how many elephants need to be weighed so the average weight will be accurate to within 350 pounds?
A.74;B.32;C.45;D.38
------
n = [1.96*1000/350]^2 = 32 when rounded up
