Question

Point estimate (sample mean) - 79.8853

Standard deviation - 22.0983

Sample size - 10

Estimate the Parameters using a 99% confidence level.

-What is the Margin of Error?

-What is the Lower Limit?

-What is the Upper Limit?

-What is the Interval Estimate?

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
