(a) Find a 95% CI for m when n = 10 and x = 1000. (b) Find a 95% CI for m when n = 25 and x = 1000. (c) Find a 99% CI for m when n = 10 and x = 1000. (d) Find a 99% CI for m when n = 25 and x = 1000. (e) How does the length of the CIs computed change with the changes in sample size and confidence level?
