In general, you compute the 95% confidence interval for the mean with the following formula:Lower limit = M - Z.95σm Upper limit = M + Z.95σmwhere Z.95 is the number of standard deviations extending from the mean of a normal distribution required to contain 0.95 of the area and ...
Other things being equal, the confidence interval for the mean will be wider for 95% confidence than for 90% confidence. 参考答案:对 点击查看答案
