# Question

Determine the sample size for the estimate of µ for the following.

a. E = 2.3, σ = 15.40, confidence level = 99%

b. E = 4.1, σ = 23.45, confidence level = 95%

c. E = 25.9, σ = 122.25, confidence level = 90%

a. E = 2.3, σ = 15.40, confidence level = 99%

b. E = 4.1, σ = 23.45, confidence level = 95%

c. E = 25.9, σ = 122.25, confidence level = 90%
