Answer:
Number of students ; 60
Explanation:
Using the formula for p +- z * Sqrt ( pq/n )
Let us first calculate the Margin of Error
= 0.816 –0.7 = 0.116
•z* = 1.96
P = (0.584 + 0.116 ) = 0.7
Q = 1- p = 1 – 0.7 = 0.3
Now inserting the values in the formula; we get
0.116 = 1.96 x sqrt { ( 0.7 x 0.3) / n }
Solving the above equation
N = 60 (rounded off to nearest number)
Hence the number of students that were selected by the environmental teacher in the sample is 60
