(4) Another (and a more universal approach) to get rid of the dependence on $\theta$ in (2) is to estimate $s$ via the sample
standard error and use approximation of $\bar{X}$ via Student t-distribution; see details in Ross textbook on statistics or in the lecture notes
```{r}
for (n in c(100, 1000, 10000)) {
cat("FOR SAMPLE SIZE = ", n, ":\n")
sample_exp = rexp(n*m, lambda) # creating a single sample of exponential distribution
sample_means = colMeans(matrix(sample_exp, nrow=n)) # creating a sample of sample means
