Researchers conducted a study to find out if there is a difference in the use of eReaders by different age groups. Randomly selected participants were divided into two age groups. In the 16- to 29-year-old group, 7% of the 630 surveyed use eReaders, while 11% of the 2,303 participants 30 years old and older use eReaders. (Use ? = 0.05. For subscripts let 1 = 16- to 29-year-old users, and 2 = 30 years old and older users.) State the Distribution of the test: P'1- P'2 ~ N( _ , _ ). I found the standard deviation as .0136. So now I just need the fill in. P'1- P'2 ~ N( x , .0136). What is x? Thank you!

Question
Researchers conducted a study to find out if there is a difference in the use of eReaders by different age groups. Randomly selected participants were divided into two age groups. In the 16- to 29-year-old group, 7% of the 630 surveyed use eReaders, while 11% of the 2,303 participants 30 years old and older use eReaders. (Use ? = 0.05. For subscripts let 1 = 16- to 29-year-old users, and 2 = 30 years old and older users.)
State the Distribution of the test: P'1- P'2 ~ N( _ , _ ).
I found the standard deviation as .0136. So now I just need the fill in.
P'1- P'2 ~ N( x , .0136). What is x? Thank you!
