举一反三
- The larger the level of confidence used in constructing a confidence interval estimate of the population mean, the narrower the confidence interval.
- So-called “95% confidence interval for population mean” is applied to estimate the location of population mean, with a confidence level 95%.
- In order to construct a confidence interval estimate of the population mean, the value of the population mean is needed.
- When a range of values is used to estimate a population parameter, it is called _______. A: a point estimate B: an interval estimate C: a statistical parameter D: a range estimate
- The standard error of estimate is based on:? squared deviations from the regression line.|negative values.|squared units of the independent variable.|the regression mean square error.
