A new species of sea snail is discovered in southern Louisiana. They randomly sample 38 of the new snails in their collection and find the mean weight of this sample to be 31.7 grams.

Using a significance level of 0.05, test the claim the the mean weight of this new species of snail is greater than 30 grams. Be sure to report the p-value and write an interpretation in terms of the claim that we have been told to test
