Answer:
415
Step-by-step explanation:
Confidence Level = 98%
Z-value for this confidence level = z = 2.326
Margin of error = E = 0.08
Mean = u = 6.6
Standard deviation =
Required Sample Size = n = ?
The formula for margin of error is:
Re-arranging the equation for n, and using the given values we get:
Thus, the minimum sample size required to create the specified confidence interval is 415
