Mike thinks that there is a difference in quality of life between rural and urban living. He collects information from obituaries in newspapers from urban and rural towns in Idaho to see if there is a difference in life expectancy. A sample of16 people from rural towns give a life expectancy of x = 71.5 years with a standard deviation of S₁ = 6.6 years. Asample of 6 people from larger towns give x = 74.3 years and su = 9.52 years. Does this provide evidence that peopleliving in rural Idaho communities have different life expectancy than those in more urban communities? Use a 1% level ofsignificance.(a) State the null and alternative hypotheses: (Type "mu_r" for the symbol µ,, e.g. mu_r not = mu_u for the meansare not equal, mu_r > mu_u for the rural mean is larger, mu_r < mu_u, for the rural mean is smaller.)Ho =Ha=(b) The degree of freedom is(c) The test statistic is●‒‒—……TTT…………

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.” Identify the reason for mean incomes for households being higher than median incomes for households.

Please help me better understand word problem. A researcher was investigating variables that might be associated with the academic performance of high school students. The data included the average Math SAS score of all high school seniors in the city that took the exam (labeled as the variable SAT-M), the average number of dollars per pupil spent on education by the city (labeled as the variable $Per Pupil), and the percentage of high school seniors in the city that took the exam (labeled as the variable %Taking). As part of the researcher's investigation, he ran the following multiple linear regression model as SAT-M=Beta0 + Beta1($Per Pupil) + Beta2(%Taking). This model was fit to the data using the method of least-squares, results shown inside of table within photo. Question: What's the 95% confidence interval for Beta1, (coefficient of variable $PerPupil). Then determine the interpretation for Beta2 (coefficient of %Taking variable).
