I'm having trouble finding the P-Value and the Test of Significance: Zcrit and Ztest. This is data for pH values for electrode and optical)
here is what I have
the hypothesis is
H0: µe = µo
Ha: µe ≠ µo
(e= electrode and o = optical)
ờo = 0.035
ờe = 0.021
here is all my work

untill i can upload the stuff to a better site. just copy the link and paste it in browser.
Z= (Xbar -µ)/(ờo)
Z= (Xbar -µ)/(ờe)
