Step-by-step explanation:
Margin of error = critical value × standard error
At 99% confidence, the critical value is z = 2.576.
The standard error is σ/√n = 5.4/√n.
Given the desired margin of error is 0.65:
0.65 = 2.576 × 5.4/√n
n = 458

In order to find what 10% of a day is:
A day is 24 hours long.
Divide 24 by 100, then multiply the answer by 10.
24/100=0.24
0.24*10=2.4
So, 10% of the day is 2.4 hours.
2 hours and 30 minutes can be written as a decimal as 2.5.
So, 2 hours and 30 minutes is slightly more than 10% of the day.
