LOS e: Explain and interpret the p-value as it relates to hypothesis testing.
An analyst is testing the hypothesis that the mean excess return from a trading strategy is less than or equal to zero. The analyst reports that this hypothesis test produces a p-value of 0.034. This result most likely suggests that the:
|
A) |
null hypothesis can be rejected at the 5% significance level. | |
|
B) |
best estimate of the mean excess return produced by the strategy is 3.4%. | |
|
C) |
smallest significance level at which the null hypothesis can be rejected is 6.8%. | |
A p-value of 0.035 means the hypothesis can be rejected at a significance level of 3.5% or higher. Thus, the hypothesis can be rejected at the 10% or 5% significance level, but cannot be rejected at the 1% significance level.
