Question 1 A factory investigated four different methods of preparing the superconducting compound PbMo.Ss. They contend...
An article in Materials Research Bulletin investigated four different methods of preparing the superconducting compound PbMo6S8. The authors contend that the presence of Oxygen during the preparation process affects the material’s superconducting transition temperature. Preparation methods 01 and 03 use techniques that are designed to eliminate the presence of Oxygen, and methods 03 and 04 allow Oxygen to be present. Five observations on Transition Temperature were made for each method, and the results are given in the table: Preparation Method...
An article in the material 13-12. An article in the Materials Research Bulletin (1991, Vol. 26(11)] investigated four different methods of preparing the superconducting compound PbMo S. The authors contend that the presence of oxygen during the preparation process affects the material's superconducting transition temperature T. Preparation methods 1 and 2 use techniques that are designed to eliminate the presence of oxygen, and methods 3 and 4 allow oxygen to be present. Five observations on T. (in ®K) were made...

We are interested in the relationship between the compensation of Chief Executive Officers (CEO) of firms and the return on equity of their respective firm, using the dataset below. The variable salary shows the annual salary of a CEO in thousands of dollars, so that y = 150 indicates a salary of $150,000. Similarly, the variable ROE represents the average return on equity (ROE)for the CEO’s firm for the previous three years. A ROE of 20 indicates an average return...
