Question: Using the large sample confidence interval formula for ???????? ????????, compute a 95% (a) lower bound confidence interval for ???????? ???????? when ????????
Using the large sample confidence interval formula for ???????? − ????????, compute a 95%
(a) lower bound confidence interval for ???????? − ???????? when ???????? = 60, ???????? = 52, ˆ???????? = 0.37, and ˆ???????? = 0.44.
(b) lower bound confidence interval for ???????? − ???????? when ???????? = 100, ???????? = 150, ˆ???????? = 0.74, and ˆ???????? = 0.62.
(c) upper bound confidence interval for ???????? − ???????? when ???????? = 198, ???????? = 212, ˆ???????? = 0.28, and ˆ???????? = 0.19.
(d) upper bound confidence interval for ???????? − ???????? when ???????? = 300, ???????? = 300, ˆ???????? = 0.65, and ˆ???????? = 0.51.
