Assume that a simple random sample has been selected from a normally distributed population. Find the test statistic, P-value, critical value(s), and state the final conclusion.
-A cereal company claims that the mean weight of the cereal in its packets is at least 14 oz. The weights (in ounces)of the cereal in a random sample of 8 of its cereal packets are listed below. $$\begin{array} { l l l l l l l l }
14.6 & 13.8 & 14.1 & 13.7 & 14.0 & 14.4 & 13.6 & 14.2
\end{array}$$ At the 0.01 significance level, test the claim that the mean weight is 14 ounces.
