If the facts are:
Ho: mu = 275 vs Ha: mu > 275
N = 500
df = n-1 or 499
Xbar =280
S = 25
Calculated test statistic is 4.47
If asked to supposes the test statistic was 2.67 how would one calculate the associated p-value?
Am I using the Student's t Table and calculating for a one-sided p value or some other procedure and table?
