1.Sap software company is conduction a two-tailed test of means but the new developmental software program only calculates a one-tailed p-value equal to 0.19. the actual p-value for your test is:

  1. 0.19
  2. 0.095
  3. 0.38
  4. 2*0.095
  5. Need more infor to calculate this valu

2.One-way anova uses a one-tail hypothesis while two-way anova uses a two-tail hypothesis test.

Ture or False
