If there are potential outliers, select the corresponding numbers of charity organizations as indicated in the Excel Online file above. If there are no potential outliers, select "None". 3 b. Develop an estimated regression equation that could be used to predict program expenses (%) given fundraising expenses (%). Program Expenses % (pred) = [90.94 + -0.91 Fundraising Expenses (%) (to 2 decimals) c. Does the value for the slope of the estimated regression equation make sense in the context of this problem situation? Thus, for every 1% increase in the amount spent on fundraising by 0.91 %. The negative slope and value seem to The slope of the estimated regression equation is -0.91 the percentage spent on program expresses will decrease make sense in the context of this problem situation (to 2 decimals). d. Use residual analysis to determine whether any outliers and/or influential observations are present. Briefly summarize your findings and conclusions. is an outlier because it has the largest absolute value of the standardized residual. Observation 3 Observation 5 is an influential observation because it has the highest leverage.
