If Ho: μ = 50 and Ha: mu. = 59 and s = 10 what is αlpha if x exceeds 56for n=25

Do you mean 59 or 56?
Z = (scoremean)/SD
Z = (mean1  mean2)/standard error (SE) of difference between means
SEdiff = √(SEmean1^2 + SEmean2^2)
SEm = SD/√n = 10/√25 = ?
If only one SD is provided, you can use just that to determine SEdiff.
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score.
