Question 670820
the mean of this data is equal to 4,541
the standard deviation is equal to 1008.
the point estimate of this data is the mean.
at 95% confidence level, the range of possible values you can expect in a sample of the same size 95% of the time would be equal to +/- 1.96 standard deviations about the mean which would be calculated as 4541 - 1008 * 1.96 to 4541 + 1008 * 1.96.
that would make the interval estimate from 2565.3 to 6516.7
the point estimate is 4541.
the standard deviation is 1008.
