Missing question: How many executives should be surveyed?
Solution:
Mean = 13 hours
SD = 3 hours
Confidence level = 95%
Mean viewing time within a quarter of an hour = 0.25 = 1.96*3/sqrt (N)
Where N = Sample population
N = {(1.96*3)/0.25}^2 = 553.19 ≈ 554
Therefore, 554 executives should be surveyed to yield such results.
A has 27,000 seats, B has 14,
200 seats, and C has 12,800 seats
Every square is a rectangle because it is a quadrilateral with all four right angle (a rectangle is not a square)
