Vincent randomly selected a bag of M&Ms from a randomly selected gas station as he was driving down the interstate. Being bored while riding in the car, he decided to evaluate his green M&Ms. From this simple random sample, there were 19 green M&Ms with a sample mean weight of 0.8635 grams and a sample standard deviation of 0.0570 grams. Use a 0.05 significance level to test the claim that the mean weight of all M&Ms is equal to 0.8535 (which is the mean weight required so that M&Ms have the weight printed on the packaged label)
