Use the grey star to mark the mean of the sample. (Be sure to place the star on the horizontal blue Iline segment
that represents the confidence interval.)
To construct the confidence interval, the quantity tsm is subtracted from and added to the sample mean.
In this case, tsm
Suppose that the researcher uses the same sample but decides to construct a 85% confidence interval of the mean
of the population.
Compared with the center of the 95% confidence interval, the center of the 85% confidence interval
Compared to the 95% confidence interval, the 85% confidence interval
At the same confidence level,
in the sample size would have a similar effect on the width of the
confidence interval as changing the confidence level from 95% to 85%.

Suppose the mean of a population is u = 22. A researcher (who does not know that µ =
22) selects a random sample
of size n from this population. Then she constructs a 95% confidence interval of the population mean.
