I performed a t-test for two independent samples. But the value of T that the test returns (2.9552) is not within the confidence interval that the test generates ( 0.4772928 2.4227072).
Does anyone know why this happens?
Can it be fixed?
t.test(Oan, Ofa, alternative = "two.sided", var.equal = FALSE)
Welch Two Sample t-test
data: Oan and Ofa
t = 2.9552, df = 106.73, p-value = 0.003846
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
0.4772928 2.4227072
sample estimates:
mean of x mean of y
4.30 2.85
