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.
If x represents the number of students from country C.
then 122% of x = 116,000
122/100 * x = 116000
Transposing the formula for x;
therefore x = 116000 * 100/122 = 95,082 students
