The City Council proposed to utilize a government-ownedland with an area of 15, 000 square meters. One-third of the areawill be used to plant mango trees while the rest of the land iswhere an emergency field hospital shall be built. As the cityengineer, you were tasked to determine the following:The rate at which the total average of COVID cases isdx= 1 tent per day, givendtincreasing at x = 10 tents andthan if 25 tents are built, the average number of COVIDcases per tent will be 6 cases while the average number ofcases will increase by 2 per tent for each additional tent inthe same area due to overcrowding.

Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost estimating purposes, managers use two hours of labor time for the planting of a medium- sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours).

A magazine provided results from a poll of 1500 adults who were asked to identify their favorite pie. Among the 1500 respondents, 13% chose chocolate pie, and the margin of error was given as t4 percentage points. Describe what is meant by the statement that "the margin of error was given as ±4 percentage points." Choose the correct answer below. O A. The statement indicates that the interval 13% + 4% is likely to contain the true population percentage of people that prefer chocolate pie. O B. The statement indicates that the study is 100% - 4% = 96% confident that the true population percentage of people that prefer chocolate pie is 13%. C. The statement indicates that the study is only 4% confident that the true population percentage of people that prefer chocolate pie is exactly 13%. O D. The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 13% +4%.
Your local gas company is interested in estimating the average usage during the month of January. A random sample of 1280 households found the following results: X= 82 therms and s=28 therms. Conduct a test of hypothesis to determine if the average amount exceeds 80 therms. Use a=0.02.

PT. X is an industry engaged in concrete steel with various diameter sizes. The product that is mostly produced is concrete iron with a diameter of 12 mm because it suits the needs of consumers and the current pandemic conditions. During the period from January to December 2019, PT. X is capable of producing as many as 6800 tonnes of units. From the results produced, there is a product defect of 70.4 with the type of product damage, namely overfill (wing), overlap (excessive shape), underfill (kempong) and scratch (beret). In that period, defects were found above the tolerance limit of 2%, namely at week 5 and week 12 of 2.42% and 2.21%. During the production process PT.X has a 2% probability of producing defective products. If you check is 065, then determine:a. P(X=0)b. P(X=1)c. P(X=2)d. P(X≤2)e. P(X≥3)

A typical treatment for Acinetobacter baumannii infection, for example, is a regimen of ampicillin, consisting of 250 mg, 4 times a day for 1 week. But antibiotics are used for a variety of medical issues by many people in the United States. Based on this information, estimate the weight, in kilograms, of ALL antibiotics ingested by people in the US each year. State any other assumptions and show all of your work.
