Two-Sample Equal Variance t-Test

ttest(x, y, alpha = 1/20, alternative = "two.sided", ...)

Arguments

x

a non-empty numeric vector.

y

a non-empty numeric vector.

alpha

value to test hypothesis.

alternative

hypothesis (can take on one of three values).

...

further arguments to be passed to or from methods.

Value

the answers!
