APFIVE Sample Size and Precision of Estimates
In statistical inference, what is the primary effect of increasing the sample size on an estimate of a population parameter?
A
It widens the confidence interval, providing a broader range of plausible values
B
It increases the p-value, making it easier to reject the null hypothesis
C
It decreases the power of the test, reducing the likelihood of Type I errors
D
It reduces the standard error, leading to more precise estimates of population parameters
