An article in Urban Ecosystems, "Urbanization and Warming of Phoenix (Arizona, USA): Impacts, Feedbacks and Mitigation" (2002, Vol.6, pp. 183–203), mentions that Phoenix is ideal to study the effects of an urban heat island because it has grown from a population of300,000 to approximately 3 million over the last 50 years and this is a period with a continuous, detailed climate record. The 50-yearaverages of the mean annual temperatures at eight sites in Phoenix are shown below. Check the assumption of normality in thepopulation with a probability plot. Construct a 90% confidence interval for the standard deviation over the sites of the mean annualtemperatures.SiteSky Harbor Airport 23.3Phoenix Greenway 21.7Phoenix Encanto 21.6WaddellLitchfieldAverage Mean Temperature (°C)LaveenMaricopaHarlquahala21.721.320.720.920.1 SiteSky Harbor Airport 23.3Phoenix Greenway 21.7Phoenix Encanto 21.6WaddellLitchfieldLaveenAverage Mean Temperature (°C)MaricopaHarlquahalai21.721.320.720.920.1Round the answers to three decimal places.≤0≤ i

Question The relationship between United States unemployment and inflation rates during the Covid-19 pandemic. Background The covid-19 pandemic has led to higher unemployment rates in the United States than normal because many people were laid off jobs in response to the pandemic (Al-Fadly, 2020). It is important to analyze how such as sharp increase in unemployment affected inflation in relation to how unemployment have traditionally affected inflation. The overall relationship between unemployment and inflation has traditionally been an inverse one. It is argued that when unemployment rates are higher, the number of individuals who are looking for jobs usually becomes higher than the number of job positions that are available (Putnam & Azzarello, 2015). In such a situation, employers tend to pay lower wages because there is abundance of workers which naturally leads to a lower wage inflation. This study will examine the relationship between unemployment rates and inflation…

Question 4 Beachcomber Ltd in a local car dealership that sells used and new vehicles. The manager of the company wants to know how different variables affect the sales of his vehicles. A random sample of yearly data was taken with the view to testing the model: SALES=a+BAGE+YMIL+&ENG Where SÄLES= amount that a vehícle is sold for($000's), AGE = age of the vehicle, MIL= the total mileage of the vehicle at the point of sale and ENG= the size of the engine.

Section 10.1 Question #8 Listed below are amounts of court income and salaries paid to the town justices. All amounts are in thousands of dollars. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using α=0.05. Is there sufficient evidence to conclude that there is a linear correlation between court incomes and justice salaries? Based on the results, does it appear that justices might profit by levying larger fines? Court Income 66.0 406.0 1566.0 1131.0 270.0 250.0 111.0 153.0 32.0 Justice Salary 31 46 91 58 48 61 25 26 18 The linear correlation coefficient is r= _________. (Round to three decimal places as needed.) The test statistic is t= __________. (Round to three decimal places as needed.) The P-value is ________. (Round to three decimal places as needed.)
