- Use theorem 5.4.3 to form a proportion in which TS is a geometric mean. Hint: TVSTSR Exercises 1-6The 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)?Answer accurately otherwise downvoted and reported.Give detailed explantions.

- Engr. Janry Garcia and Engr. Caroline Moncada is working on a project for a newly constructed 4-story building. The project is regarding CCTV installation. As project engineers, they need to assess and make an inventory of the primary materials to be installed in the building. The following primary materials give the merchandise with its corresponding price list. C=CCTV Camera worth P5000 each; W=Cable wires P100 per meter; S=Splitters worth P50 each and B=Balun and Connectors for P150. Each of the materials should be distributed depending on the number of units per floor. For the 1st floor: twice the number of CCTV cameras is needed, three times the length of cable wire is required, four times the number of splitters and five times the number of baluns and connectors less is necessary, which gives an acceptable loss of -60dB. For the 2nd floor: 6 times the number of CCTV cameras are required, seven times the length of cable wire is needed, eight times the number of splitters less and…A 2014 Honda Civic hybrid costs $24,635. This car is supposed to get 44 miles per gallon in regular city driving and 47 mpg on the highway.2 A completely gas‐powered 2014 Honda Civic costs $18,390. This car is supposed to get 30 mpg in city driving and 39 mpg on the highway.3 1. What additional information is necessary to determine how much money will be spent on gas in a year of driving one of these vehicles? Write down some reasonable values for any missing information. 2. If you purchase the hybrid Civic, how much money would you save in gasoline purchases the first year? 3. How long would it take for the gasoline savings to make up for the additional cost of the hybrid?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…
