To estimate the mean of a normal population whose standard deviation is 6,with a bound on the error of estimation equal to 1.2 and confidence level 99% requires a sample size of at least:
A) 166
B) 167
C) 13
D) None of these choices.
Error of Estimation
The difference between a population parameter and its estimate derived from a sample.
Standard Deviation
A statistical measure that quantifies the amount of variation or dispersion of a set of values.
Confidence Level
The probability or likelihood, expressed as a percentage, that a confidence interval actually includes the true parameter value.
