using 5 step and z or t score table

using 5 step and z or t score table Problem 2. A

Problem 2. A simple random sample of the weights of 19 green M&Ms has a mean of 0.8635 g. Assume that the sample standard deviation is known to be 0.0565 g. Use a 0.1 significance level to test the claim that the mean weight of all green M&Ms is equal to 0.8541 g (which is the mean weight required so that M&Ms have the weight printed on the package label)
