Concerning inference on two independent population means, the pooled variance estimate is:


▸

a way of estimating variance that relies on the information provided by only one of the samples.



▸

an unbiased estimator of the parameter\(\style{font-family:Times New Roman;}{\sigma_1^2-\sigma_2^2}\).



▸

a combined (using a weighted average) estimate for the unknown variance of two populations.



▸

a less efficient but easier way of estimating population variances as compared to using two separate variance estimates (one for each population).
