Construct Hypothesis Testing for Questions 1 and 2 Just Formulate the hypotheses for Questions 3 and 4. 1. Bags of a certain brand of tortilla chips claim to have a net weight of 15 ounces. A representative of a consumer advocacy group wishes to see if there is any evidence that the mean net weight is 15 ounces as advertised. For this, the representative randomly selects 16 bags of this brand and determines the net weight of each. He finds the sample mean to be 14.72 and the sample standard deviation to be 0.26. Use these data to perform an appropriate test of the hypothesis at a 10% significance level. What is your conclusion? Show your work and write all the steps. 2. A recent study revealed that the typical American coffee drinker consumes an average of 3.5 cups per day.
