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
According to a continuous study conducted by the NASA's Goddard institute, the Earth's average global temperature has risen by 0.8 degrees Celsius or 1.4 degrees Fahrenheit since 1880. Since the beginning of the Industrial Revolution, the thermometer readings have risen continuously.
