Let's say I have two samples and I want to calculate confidence intervals for the means of each sample.
x = rnorm(10)
y = rnorm(10)
Using the t.test command I'm able to get the following output.
> t.test(x, y)
Welch Two Sample t-test
data: x and y
t = -0.0104, df = 17.17, p-value = 0.9918
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
-1.077822 1.067245
sample estimates:
mean of x mean of y
-0.2235438 -0.2182557
However, what if I want the 95% confidence intervals for each sample. Is that a manual calculation I have to do. I want to generate confidence intervals for each sample so that I can compare the two in regards to whether I should reject the null hypothesis.
Basically, I want to mimic this in R.
