Show complete solution 1. A random sample of 40 packs of certain brand of marshmallow have a mean weight of 7.5 grams with a standard deviation of 1.12 grams. If the manufacturer claims that the mean weight is 8.2 grams, is there a significant difference between the sample mean and the population mean? Use 0.05 significance level. I. State the Null and Alternative Hypotheses IV. Compute for the computed value Given: Choose the appropriate statistical test III. Determine the Level of Significance and the V. Make the Decision and Conclusion Critical Value
