An estimate of the standard error for a t-test of independent means that assumes that the variances of both groups are equal is called the:
A) mean squared standard error estimate.
B) pooled estimate of the standard error.
C) significance error estimate.
D) between-group standard error.

The estimate of the standard error for a t-test of independent means that assumes equal variances between the groups is called the pooled estimate of the standard error. This estimate takes into account the sample sizes and variances of both groups, providing a more accurate estimate of the standard error than using either group's variance alone. The other options listed are not accurate descriptions of this estimate.
