Question

Statistics question Please help I am not sure if i am right or on the right track...

Answer 1

Express the confidence interval (0.042,0.134) in the form of p^-E<p^+E

phat= (0.042+0.134)/2
phat=(0.176)2
phat=0.088

E=0.134-0,088
E=0.046

0.088<p<0.046

Answer 2

correct?

Answer 3

No. You went past your mark.

Find p-hat (0.042+0.134)/2 = 0.176/2 = 0.088 -- Perfect.

Find E (0.134-0.042)/2 = 0.092/2 = 0.046

0.088 - 0.046 < 0.088 + 0.046

Checking, just for fun.

0.088 - 0.046 = 0.042 Good
0.088 + 0.046 = 0.134 Good
