Asked by Desmond Thomas on Apr 24, 2024
When a researcher increases the confidence level from 95% to 99%, the wider interval implies ______.
A) increased precision in estimating the population mean
B) a lower confidence that the interval contains the population mean
C) a loss of precision in estimating the sample mean
D) decreased precision in estimating the population mean
Confidence Level
The proportion of times that an estimating procedure will produce intervals that contain the parameter of interest if the same population is sampled repeatedly.
Precision
The degree to which repeated measurements under unchanged conditions show the same results.
- Become cognizant of the relationship between certainty measures and interval ranges.
- Acquire insight into the impact that adjustments in confidence levels have on the precision of confidence intervals.
