Function which performs a 2-sample t-test using sample statistics (mean, sd, n) instead of a lists of observations. Not recommended for use outside gg_ttest_between().

1	t_test2(mean1, mean2, sd1, sd2, n1, n2, m0 = 0, equal.variance = TRUE)

`mean1`	Mean for sample 1
`mean2`	Mean for sample 2
`sd1`	Standard deviation for sample 1
`sd2`	Standard deviation for sample 2
`n1`	Number of replicates for sample 1
`n2`	Number of replicated for sample 2
`m0`	Difference in means to test for. Default is 0.
`equal.variance`	Optional – Boolean for whether variances are equal. TRUE results in a student's t-test. FALSE results in a Welch test. Defaults to TRUE.
