Respuesta :
So when parent population is right-skewed and the sample size is small, the percentage of intervals that include population mean is (above, below, equal to) 0.95 when building 95% confidence intervals for said mean.
Explain the term confidence interval?
A confidence level of both the CI refers to the likelihood that its confidence interval contains the actual population mean value.
- Any confidence level can be used to determine a CI, although 95% is the most typical value.
- A 95% confidence interval, strictly speaking, means that if we generate a 95% confidence interval each of 100 independent samples, then about 95 of a 100 confidence intervals include the true mean value (μ).
Thus, when parent population is right-skewed and the sample size is small, the percentage of intervals that include population mean is (above, below, equal to) 0.95 when building 95% confidence intervals for said mean.
