- Q1. The management of an oil company is trying to decide whether to drill for oil in a particular fieldin the Gulf of Mexico. It costs the company $600 thousand to drill in the selected field. Themanagement believes that if oil is found in this field, its estimated value will be $3400 thousand. Atpresent, this oil company believes that there is a 45% chance that the selected field actually containsoil. Before drilling, the oil company can hire a team of geologists to perform seismographic tests at acost of $55 thousand. Based on similar tests in other fields, the tests have a 25% false negative rate(no oil predicted when oil is present) and a 15% false positive rate (oil predicted when no oil ispresent).A. Assume the oil company wants to maximize its expected net earnings. Please utilize decisiontree analysis to determine its optimal strategy.B.

She collected the data in the graph above from records on horses she had worked with in the past (shown by the blue dots) and fit a linear regression equation (shown by the red line). According the regression equation, as the age of the horse increases in days. the wither height in cm Select an answer v The age of the horse in days and the wither height in cm are Select an answer The slope of the regression equation is approximately 0.044. interpret the slope by completing the sentence below. As the Select an answer v increases by 1, the Select an answer V increases by The regression equation approximates the wither height by the following formula.
