(to 2 decimals) Does the value for the slope of the estimated regression equation make sense in the context of this problem situation? The slope of the estimated regression equation is . Thus, for every 1% increase in the amount spent on fundraising the percentage spent on program expenses will decrease by %. The negative slope and value seem to make sense in the context of this problem situation (to 2 decimals). Use residual analysis to determine whether any outliers and/or influential observations are present. Briefly summarize your findings and conclusions. Observation is an outlier because it has the largest absolute value of the standardized residual. Observation is an influential observation because it has the highest leverage. 6 Volunteers of America 927095339 8.6 1.8 89.2 7 Dana-Farber Cancer Institute 875935857 13.2 1.5 85.2 8 AmeriCares 855321080 0.4 0.7 98.5 9 ALSAC - St. Jude Children's Research Hospital 830746457 9.6 16.7 73.2 10 City of Hope 734318299 13.4 3.1 82.9

A statistical program is recommended. Consider the following data for two variables, x and y. xi 135 110 130 145 175 160 120 yi 145 105 125 120 130 130 110 (a) Compute the standardized residuals for these data.

(Round your answers to two decimal places.) The standardized residual with the largest absolute value is _____, corresponding to yi = ______ . (b) Charity Navigator is America's leading independent charity evaluator. The following data show the total expenses ($), the percentage of the total budget spent on administrative expenses, the percentage spent on fundraising, and the percentage spent on program expenses for 10 supersized charities. Administrative expenses include overhead, administrative staff and associated costs, and organizational meetings. Fundraising expenses are what a charity spends to raise money, and program expenses are what the charity spends on the programs and services it exists to deliver. The sum of the three percentages does not add to 100% because of rounding.

These are supposed to be correct per guided video. The excel file has only one decimal and Cengage asks for 2. I don't know if that is the problem and if so what to do, or if there is something going on.

Determine the regression equation. (Round your answers to 3 decimal places.) Is there a direct or indirect relationship between the distance from the fire station and the amount of fire damage? How much damage would you estimate for a fire 5 miles from the nearest fire station? (Round your answer to the nearest dollar amount.) Determine and interpret the coefficient of determination. (Round your answer to 3 decimal places.) Fill in the blank below. (Round your answer to one decimal place.) Determine the correlation coefficient. (Round your answer to 3 decimal places.) Choose the right option. How did you determine the sign of the correlation coefficient? State the decision rule for 0.01 significance level: H0 : ρ = 0; H1 : ρ ≠ 0. (Negative value should be indicated by a minus sign. Round your answers to 3 decimal places.) Compute the value of the test statistic. (Round your answer to 2 decimal places.) Is there any significant relationship between the distance from the fire station and the amount of damage? Use the 0.01 significance level. Exercise 13-60 (Algo) (LO13-5) Waterbury Insurance Company wants to study the relationship between the amount of fire damage and the distance between the burning house and the nearest fire station. This information will be used in setting rates for insurance coverage. For a sample of 30 claims for the last year, the director of the actuarial department determined the distance from the fire station (x) and the amount of fire damage, in thousands of dollars (y).
