Oil Well Drilling CostsEstimating the costs of drilling oil wells is an importantconsideration for the oil industry. DS 12.2.1 contains thetotal costs and the depths of 16 offshore oil wells locatedin the Philippines (taken from “Identifying the majordeterminants of exploration drilling costs: A firstapproximation using the Philippine case" by Gary S.Makasiar, Energy Exploration and Exploitation, 1985).(a) Fit a linear regression model with cost as the dependentvariable and depth as the explanatory variable.(b) What does your model predict as the cost increase foran additional depth of 1000 feet?(c) What cost would you predict for an oil well of 10,000feet depth?(d) What is the estimate of the error variance?(e) What could you say about the cost of an oil well ofdepth 20,000 feet?

X to $ X (c) If an accounting cost report at the end of next month shows that the actual production cost during the month was $6,700, should managers be concerned about incurring such a high total cost for the month? Discuss. Since $6,700 is within the prediction interval, managers should not be concerned about Incurring such a high total cost for one…
Fit these three regression models and then discuss the similarities and differences between them, particularly as relates to slope estimates (use CI’s) and R2. Also address why this is a “special case” and we wouldn’t necessarily expect to see these model characteristics for a typical dataset. a) Additive model including both predictors (output attached) b) Model including only Moisture (output attached) c) Model including only Sweetness BrandLiking = 68.62 + 4.38 Sweetness Term 95% CI P-ValueConstant (50.16, 87.09) 0.000Sweetness (-1.46, 10.21) 0.130 S R-sq R-sq(adj)10.8915 15.57% 9.54%

A group of Maternal and Child Health public health practitioners are interested in the relationship between depression and a number of health outcomes. Suppose the research team gathers information on a group of participants, and constructs a multiple linear regression model looking at the relationship between depression and household income dichotomized as above and below the federal poverty line controlling for a number of potential confounders. The following is a computerized output displaying the results of their analysis.
