An article presents a method, based on a modal pushover analysis, of estimating the hysteretic energy demand placed on a structure by an earthquake. a sample of 18 measurements had a mean error of 457.7 knm with a standard deviation of 317.7 knm. an engineer claims that the method is unbiased, in other words, that the mean error is 0. can you conclude that this claim is false? find the p-value and state a conclusion.
