A chip company claims that their 28 gram bags of chips contain an average of at most 36.5 milligrams of factory filth. To test this claim, you take a simple random sample of thirty 28 gram bags of chips. You find the sample has a mean factory filth content of 37.4 milligrams. Assume the population is normally distributed and the population standard deviation σ= 2.8 milligrams. At α= 0.10 , can you reject the company's claim?   Write the null and alternative hypotheses for the given claim using the appropriate symbols. Sketch a graph showing the rejection and non-rejection regions. Determine the value of the test statistic and the outcome of the test
