Answer:
The minimum sample size is n = 75 so that the desired margin of error is 5 or less.
Step-by-step explanation:
We are given the following in the question:
Population variance = 484
Standard deviation =

Confidence level = 0.95
Significance level = 0.05
Margin of error = 5
Formula:
Margin of error =


Putting values, we get

Thus, the minimum sample size is n = 75 so that the desired margin of error is 5 or less.
To determine the measure of angle C. You would solve the equation for X. X+47=180. X= 180-47. X= 133. The measure of angle C is 133 degrees.
