The research question for this research design is: Do humans commit acts of altruism? I have created a research design, and now need to determine potential complications. I am conducting a linear regression model to find the answer to my research question. Please answer the following questions: 1) What do you anticipate as complications in measuring the variables or collecting the data (such as, are there better ways to measure your conceptual variables? 2) why you have chosen to study these variables this way?

Management of a soft-drink bottling company has the business objective of developing a method for allocating delivery costs to customers. Although one cost clearly relates to travel time within a particular route, another variable cost reflects the time required to unload the cases of soft drink at the delivery point. To begin, management decided to develop a regression model to predict delivery time based on the number of cases delivered. A sample of 20 deliveries within a territory was selected. The delivery times and the number of cases delivered were organized in the following table: CUSTOMER NUMBER OF CASES DELIVERY TIME (MINUTS) 1 52 32.1 2 64 34.8 3 73 36.2 4 85 37.8 5 95 37.8 6 103 39.7 7 116 38.5 8 121 41.9 9 143 44.2 10 157 47.1 11 161 43.0 12 184 49.4 13 202 57.2 14 218 56.8 15 243 60.6 16 254 61.2 17 267 58.2 18 275 63.1…
Bill wants to explore factors affecting work stress. He would like to examine the relationship between age, number of years at the workplace, perceived social support, and work stress. He collects data on the variables from 100 employees (males and females) working in banks. The research question is How accurately can work stress be predicted from linear combination of the predictors (age, social support, number of years at the workplace)? Conduct a multiple regression analysis to answer the following questions: What is the relationship of age, number of years, and social support with work stress? Is the regression significant? If yes, what does it indicate?

Management of a soft drink bottling company has the business objective of developing a method for allocating delivery costs to customers. Although one cost clearly relates to travel time within a particular route, another variable cost reflects the time required to unload the cases of soft drink at the delivery point. To begin, management decided to develop a regression model to predict delivery time based on the number of cases delivered. A sample of 7 deliveries within a territory was selected. The delivery times and the number of cases delivered were organized in the following table: Customer No. of Cases Delivery Time 1 14 24 16 31 3 17 28 4 19 30 5 11 20 6 16 22 7 24 40 a) Use the least-squares method to compute the regression coefficients. b) Write down the estimated equation and interpret the meaning of the coefficients in this problem c) Predict the mean delivery time for 26 cases of soft drink. d) Determine the value of the extent of relationship between delivery time and…
We wants to assess the relationship between overall GPA (4.0 scale) and amount of time spent weekly on school work of 50 college students. Simple linear regression model is used and some results for the model is given: a) Is it plausible that the true intercept for the model is 2.0? Why or why not? (hint: using interval for intercept) b) If 2.0 is the real intercept for the model, does it make contextual sense? Explain why it is or why it is not. c) Using the model, calculate the number of hours needed to achieve a GPA of 4.0. Then explain why this estimate number of hours is biased. (hint: think about Y).

Could you please look at question 2. The instruction say to use a linear regression calculation tool. Isn’t this a graphing calculator? In a prior question, a rep sent a answer where I have no idea where they are getting this answer or why they are solving this problem this way. Could you please review Thank you, Ryan
