Dear Yuvraj!

❝ 90% CI for Upper limit=1.329927721 which is nearly equal to 1.33

❝ 90% CI for Lower limit=1.07998416 which is nearly equal to 1.08

❝

❝ Is it right, Sir?

Oops, you got me!
You are right – and I am wrong.
If I use values with no rounding I get exactly 1.08 and 1.33 up to the numeric precision of my machine.
Lesion learned: Never trust in an old fart with a pocket calculator too lazy to fire up some statistical software.
Terribly sorry for the confusion…
