Answer:
Option C. 705 to 784 students
Explanation:
margin error = 6%
range of students = 68 to 97
n = 1070
The margin of error is given by the formula:
ME =

where z is the critical value
p = the probability of an event happening
n = sample size
Therefore, taking the confidence level of 5 % and extrapolating in the tables, the value will range somewhere between 705 to 784 students.
