Hi!
I'm trying to find the power of a paired t-test. I used the power.t.test function, but noticed that if I increase the p-value, the power also increase. I do not understand, should not the power decrease, when the p-value increase?
power.t.test(n = 33, delta = 0.5, sd = 1, sig.level = 0.05,
power = NULL,
type = "paired",
alternative = "two.sided",
strict = T)
power=0.80
power.t.test(n = 33, delta = 0.5, sd = 1, sig.level = 0.45,
power = NULL,
type = "paired",
alternative = "two.sided",
strict = T)
power=0.98
