Acompany's old antacid formula provided relief for 70% of the people who used it. the company tests a new formula to see if it is better and gets a p-value of 0.27. is it reasonable to conclude that the new formula and the old one are equally effective?

a)
yes, because there is only a 27% chance of seeing the observed effectivness just from natural sampling. there is evidence the new formula is more effective therefore we can conclude equal effectiveness.

b)
no, we can only say there is 27% chance of seeing the observed effectiveness from natural sampling variation. there is no evidence the new formula is more effective but we cannot conclude equal effectiveness.

c)
yes, because there is only a 83% chance of seeing the observed effectivness just from natural sampling. there is evidence the new formula is more effective therefore we can conclude equal effectivness.

d)
no, we can only say there is a 83% chance of seeing the observed effectiveness just from natural sampling variation. there is no evidence the new formula is more effective but we cannot conclude equal effectiveness.
