Answer:
864 sq ft
Step-by-step explanation:
Given that a human factors expert recommends that there be at least 9 square feet of floor space in a college classroom for every student in the class.
The number of students in the class = 96
For 1 student space required = 9 sq ft
For 96 students =?
This is a question of direct variation since when number of students increase space required also would increase.
Hence we get the minimum floor space that 96 students require.
=96*9
=864 sq ft
Notice it is +/-4 times standard deviation (0.65-0.04 = 0.61, 0.69-0.04=0.65)
That's almost everything. So (D) is the answer.
