- Burning fuels in power plants and motor vehicles emits carbon dioxide (CO2), which contributes to global warming. The CO2 emissions (metric tons per capita) for countries varies from 0.02 in Burundi to 44.02 in Qatar. Although the data set includes 214 countries, the CO2 emissions of 15 countries are not available on the World Bank database. The data set is too large to display but the data for the first five countries is given. Use the full data set with data on the 214 countries to answer the questions. To access the complete data set, click the link for your preferred software format: Excel Minitab JMP SPSS TI R Mac-TXT PC-TXT CSV Crunchlt! Country CO2 Emissions (Metric Tons per Capita) Aruba 23.92 Andorra 5.97 Afghanistan 0.43 Angola 1.35 Albania 1.61 Find the mean and the median for the full data set. Round your answers to three decimal places. The mean for these data is tons per person The median for these data is tons per personShrubs that Withstand Fire Fire is a serious threat to shrubs in dry climates. Some shrubs can resprout from their roots after their tops are destroyed. One study of resprouting took place in a dry area of Mexico. The investigators first clipped the tops of all the shrubs in the study. For the treatment, they then applied a propane torch to the stumps of the shrubs to simulate a fire, and for the control the stumps were left alone. The study included 24 shrubs of which 12 were randomly assigned to the treatment and the remaining 12 to the control. A shrub is a success if it resprouts. For the shrub Xerospirea hartwegiana, all 12 shrubs in the control group resprouted, whereas only 8 in the treatment group resprouted. How much does burning reduce the proportion of shrubs of this species that resprout? Give the 95% plus four confidence interval for the amount by which burning reduces the proportion of shrubs of this species that resprout. The plus four method is particularly helpful…Can you answer #1 and #2 please
- You manage a team of 4 employees. The entire team is responsible for completing 4 projects on time. The time to complete the task is 4 weeks, and this is the time needed and is based on a 56-hour work week for each team member. Each team member will work 7 days a week, since this is a priority project and, must be completed on time. The names of the 4 team members are A, B, C, and D. Based on historical data, at least 1 of the 4 team members calls in sick at least (and only) 1 time per week. Based on this information, what is the probability that the project will be completed on time? If the probability of the project not being completed on time is > 0, what will you do to ensure that the project will be completed on time? What AI systems would you put in place to ensure that you can complete current and future projects? You are to select a strategy that is most feasible and you must justify your answer and provide an analysis.If a biker travels 33 miles in 3 hours, can you guarantee that the bike's speedometer must have read 11 mph at least once during the trip? Can you guarantee it will read 8 mph at least once during the trip? Can you guarantee it will read at least 14 mph? Support your conclusions mathematically.A sensory Psychologist wants to test if age affects a person's ability to detect changes in color presented on a computer screen. She recruits 3 different age groups (young, mid aged, elderly) to test. She also wants to know if bilingual people are different in their ability to detect color changes relative to non bilingual people, so half of the 60 participants are bilingual, the other not bilingual.

- As humans we consume food. The body extracts good things such as proteins and vitamins and throws away waste. A typical waste product is a uric acid. High levels of uric acid can be an indication of conditions such as gout, kidney disease, and cancer. For females a high level of uric acid is 6 mg/dL or more and for males a high level of uric acid is 7 mg/dL or more. Suppose, over a period of months, an adult female has taken 8 blood test for uric acid. The results of the test are shown below. results 8.9 6.27 3.99 7.42 9.94 8.99 9.17 5.65 Find a 95% confidence interval for the population mean of uric acid in this adult female's blood. (Round your answers to two decimal places.)margin of error mg/dL lower limit mg/dL upper limit mg/dL Does this confidence interval suggest that this adult female has a high level of uric acid? Explain your answer.A college bookstore must order books two months before each semester starts. They believe that the number of books that will ultimately be sold for any particular course is related to the number of students registered for the course when the books are ordered. They would like to develop a bestfitting line to predict how many books to order. From past records, the bookstore obtains the number of students registered, X, and the number of books actually sold for a course, Y , for 12 different semesters.A scatterplot of the data along with the best fitting line is presented below. a. The correlation between the two variables is r = .89. Calculate and interpret the value of r2.b. The equation for the best fitting line is Y = 9.30 + 0.673X. Explain and interpret the value of 9.30.c. How many books should the store order for a class of 50 students? Would you trust this prediction?Please answer the question. Asap. Thank you.

Because of the constantly evolving political climate around the United States, Gallup (who regularly conducts polls in the U.S.) conducted a poll just after the inauguration asking U.S. adults if they approve of the initiatives President Biden had implemented in his first few days in office. Another Gallup poll was conducted now that President Biden has been in office for a month asking U.S. adults if they approve of the initiatives President Biden had implemented after his first month in office. According to the first Gallup poll of 1500 randomly selected U.S. adults, 64% approved of the initiatives President Biden had implemented in his first few days in office. And according to the second Gallop poll of 1700 U.S. adults, 54% approved of the initiatives President Biden had implemented after his first month in office. Construct and interpret a 95% confidence interval for the change (difference) in the true proportion of U.S. adults…Hectic Repair Org. HRO) helps repair homes that are structurally weakened by minor earthquakes. After an earthquake, SmartProtect, an insurance company of some affected customers in the area estimates that the standard time to perform a preliminary damage assessment on an average-sized house would be about two hours. On behalf of the affected customers, SmartProtect is willing to pay a HRO employee doing such damage assessments $65 per hour. Suppose that Michael (an employee at HCRO who does flood damage assessment) takes three hours to complete the assessment on an average-sized house. What is Michael efficiency based on the standard time estimated by SmartProtect? a. Approximately one hundred and fifty percent. b. About one-third of an assessment job per hour c. Approximately one hundred and thirty dollars per assessment d. Approximately one hundred and ninety five dollars per assessment (before taxes) e. Approximately sixty seven percent.
