A company claims that the mean weight of its protein bars is $50$ grams. A quality control analyst samples 8 bars and obtains a sample mean of $51.2$ grams. After simulating $2000$ randomizations under the null hypothesis, $120$ simulated means are at least as large as $51.2$ grams. What is the correct interpretation of the $p$-value and the decision at $\alpha =0.05$?

Reject the null hypothesis; there is sufficient evidence that the true mean is greater than $50$ grams.

Fail to reject the null hypothesis; there is insufficient evidence that the true mean is greater than $50$ grams.
