A company has 8 grade one and 10 grade two inspectors for quality control inspection. At least 1,800 pieces musty be inspected in an 8 hour day. Grade one inspector can check 25 pieces an hour with the accuracy of 98%. Grade two inspectors can check 15 pieces an hour with the accuracy of 95%. The wage rate of grade one inspectors is birr 4 per hour, while grade two inspector is birr 3per hour. Any error made by an inspector cost birr 2 to the company. a) Formulate this problem as LPP b) Solve the LPP

show step by step and answer all questions The 102 highway has a posted speed limit of 70 miles per hour on the stretch from San Francisco to Bay Area. For a single week, the highway patrol set up a hidden radar gun to measure how many cars break the speed limit after having numerous reports of accidents on this stretch of highway. The highway patrol needs to put together an action plan if the annual proportion of vehicles who break the speed limit is over 9%. However, they could only set up the radar gun for one week. Question-The sampling method used for this situation would most likely be considered 'convenience sampling.' Find a potential fault, bais, or hidden variable in the way this sample was conducted that might skew the results. -What is the sample size,What is the proportion of vehicles who broke the speed limit over this 1 week period from Bay Area to San Francisco? -Construct a 90% confidence interval for the proportion of vehicles who break the speed limit annually. -Is…
