What's wrong with the following conclusion about a main effect where there are two factor levels:

"The p-value is .12, and our best estimate of the lift is 3%."

Assume the significance level, alpha, is .05.

a. Without doing a pairwise comparison, we don't know the estimated lift

b. If the p-value is .12, then 12% is our best estimate of the lift

c. There is nothing wrong; it is a correct conclusion

d. The lift needs to be adjusted based on the power and sample size

e. We cannot assume lift is any different than zero in this case
