--------------------IG------IB-----

Non-Germinated ---405-----341

Germinated --------386-----180

Carry out the Z-test to compare the proportions of seeds germinating for the IG and IB columns and interpret the result.

2. Relevant equations

3. The attempt at a solution

I don't know what I'm doing wrong but I'm assuming it's something because my answer is too big for the Z-table

Z = (p_{1}-p_{2})/root([(p_{1}(1-p_{1})/n_{1})+[(p_{2}(1-p_{2})/n_{2})

P_{1}= 386/791

P_{2}= 341/521

Then throw everything into the Z formula. What's wrong with this?
