Hi I know that you can’t answer every question is there anyway you can just answer question 14 please? 3:04ВackUse the following additional information to answer questions 14and 15:Another researcher, using the same data, ran the followingsimple linear regression model:SATM = L + O ($ Per Pupil) + O.The following results were obtained from statistical software:Source Sum of Squares dfModelError14022.7145727.4 49Coefficient Standard Error560.374S Per Pupil-0.012169VariableConstant16.800.003114. Based on these results, a 95% confidence interval for D, the coefficient of the variable $Per Pupil, is approximatelyA) 0.012169 0.0031.B)0.012169 0.0052.C)-0.012169 +0.0062.D)-0.012169 ±0.008315. The first researcher concluded that because the coefficient for the variable S Per Pupilwas positive in his results, spending additional money on students would have a positiveeffect on SATM scores. This researcher therefore recommended more money be spent onstudents. The second researcher concluded that because the coefficient for the variable SPer Pupil was negative in his results, spending additional money on students would havea negative effect on SATM scores. This researcher therefore recommended less moneybe spent on students. Why are these two conclusions different even though theresearchers used the same data?A) An error must have been made by one of the researchers.B) Both researchers failed to take into account that in their analyses, . the coefficient of thevariable S Per Pupil, was not statistically significant at even the 0.10 significance level.Hence, neither researcher could conclude that , was significantly different from 0.C) The researchers did not use the same set of explanatory variables in their models.D There must have been an influential observation in the data, rendering the analysesinappropriate.Use the following to answer questions 16–20:In a study on scholastic test scores of entering college freshmen,a random sample of colleges across the nation is selected and theaverage SAT Math score for the freshman class is recorded. Thecolleges are categorized according to their affiliation: Public,Private, or Church. Does it appear that freshmen entering thethree different types of schools do equally well on the SATMath?
