I cant figure out A, B, and C. Can someone help?

(2 points) When a poultry farmer uses his regular feed, the newborn chickens have normally distributed weights with a mean of $$61.1 \mathrm{oz}$$. In an experiment with an enriched feed mixture, ten chickens are born with the following weights (in ounces). $66.3,67.4,65.6,67.4,66.1,66.3,64.2,65.7,64,68.8$ Use the $$\alpha=0.05$$ significance level to test the claim that the mean weight is higher with the enriched feed. (a) The sample mean is $$\bar{x}=$$ (b) The sample standard deviation is $$s=$$ (c) The test statistic is $$t=$$ (d) The critical value is $$t^{*}=$$ (e) The conclusion is A. There is sufficient evidence to support the claim that with the enriched feed, the mean weight is greater than $$61.1$$. B. There is not sufficient evidence to support the claim that with the enriched feed, the mean weight is greater than 61.1.
