Can someone please help me with this problem. I have no clue in how to go about solving it. Thank you for your time and for your help.
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.
14.6 13.8 14.1 13.7 14.0 14.4 13.6 14.2
At the 0.01 significance level, does the sample support the company’s claim that the mean weight is at least 14 ounces? You may assume the weight of cereal packets is normally distributed
