Homework SourseA population is estimated to have a standard deviation of 8
A population is estimated to have a standard deviation of 8. We want to estimate the population mean within 1, with a 95% level of confidence. (Use z Distribution Table.)
| How large a sample is required? (Round up your answer to the next whole number.) |
Solution
z = 1.96
e=0.01
n = [(1.96*8) / 0.01]^2
n=2458624
