p1 hat- p2 hat =0.550-0.234 = 0.316

1.28 * 0.025 =0.032

Lower limit = 0.316-0.032 = 0.284

Upper limit = 0.316+0.032= 0.348

I cannot guarantee the decimal accuracy. 

p1hat -p2hat = 0.316665 =0.317 

Then

using full precision

lower limit =0.284465

upper limit =0.348866


lower limit = 0.284

upper limit = 0.349


I am supplying all these because, they may feed the answers in a particular fashion to prevent outside help
