(b) After receiving complaints from McDonald’s customers in Japan about the amount of french fries being served, the on-line news magazine ”Rocket News” decided to test the actual of the fries served at a particular Japanese McDonald’s restaurant. According to the Rocket News article, the official weight standard set by McDonald’s of Japan is for a medium sized fries to weigh 120 grams. The publication weighed the fries from 25 different medium fries they purchased and found the average weight of the fries in their sample to be 115 grams with variance of 100 grams. Research Question: Does the data suggest that the medium fries from this McDonald’s in Japan are underpacked? Use α =0.05. I computed TS correctly and it is Z = -2.5. Based upon the guidelines in 9.5, this TS leads to reject H0 . Now suppose I change α = 0.01, does the conclusion lead to accept H0 ?

The highway department wants to estimate the proportion of vehicles on a Highway at KM 25 between midnight and 5:00 A.M. The head of the department wants to see how many 18-wheel tractor trailers pass on the road. These estimates will be used to determine highway repairs and construction considerations and in highway patrol planning. The department chief asked investigators to calculate estimates of vehicles at different locations on inter-island roads over the past 7 days. From 3,481 vehicles counted there are 927 are 18-wheel drive. However, out of the total 927, there were 51 vehicles that had accidents so that the sample was calculated based on the results of a reduction in the number of accidents. Specify an approximate point for the proportion of vehicles performingtravel on KM 25 during this time period which is an 18-wheeled vehicle!(Assume the confidence level is 99%). What are the benefits of estimating value estimates in this case (analysis of the answers you have obtained)?
