Step 1 :We are given that the standard deviation (σ) is 41 pounds, the margin of error (E) is 8 pounds, and the z-score (Z) for a 98% confidence level is approximately 2.33.
Step 2 :We can use the formula for the sample size in a confidence interval estimation, which is: \(n = (Z*σ/E)^2\)
Step 3 :Substitute the given values into the formula: \(n = (2.33*41/8)^2\)
Step 4 :Calculate the value to get the sample size.
Step 5 :\(\boxed{143}\) is the sample size needed to estimate the mean weight of all female white-tailed deer with a 98% confidence level, to within 8 pounds of the actual weight.
