PROBLEM 1: A company claims that the mean weight per banana it ships is 160 grams with standard deviation of 18 grams. Data generated from a sample of 49 bananas randomly selected from a shipment indicated a mean weight of 153.3 grams per banana. Do the 49 selected bananas have lower weight than the rest? Test the claim at 0.05 level of significant. Formulate the hypothesis 1. Ho: 2. HA: 3. Glven: 5. Solve for z: n = a = 4. Test statistics: 6. z =, 7. Solve for confidence level 9. B. Confidence level:
