8.4 Confidence Interval Using t-distribution for One-Sample Mean (Unknown parameter)

07/23/2016

This lesson on inferential statistics shows you how to use the t-distribution in estimating the parameter µ given the sample mean and the population standard deviation is unknown. This estimation procedure is used when the conditions for the t-distribution is satisfied

This lesson shows you how to find the point estimate, margin of error, standard deviation of the sample, and standard error given the confidence interval and confidence level of the sample n. In solving these statistical measure, you will be working the confidence interval procedure in reverse. x-bar ± t* (sx/√n)

03:22 1. point estimate

04:01 2. margin of error

05:33 3. t* - critical value

07:03 4. sx - standard deviation of the sample

08:41 5. standard error

09:50 6. Interpreting confidence interval
