QUESTION 4 A steel manufacturing company wishes to compare the strength of the wires produced by an existing and a new process. The manufacturer will use the existing process unless the inerease in the mean strength in the new process is significant. The following data represents the strength of the steel wires made by the two processes: Process Strength of steel wires (megapascal, MPa) Existing 1365 1300 1286 1320 1350 1334 1330 13 10 New 1300 1310 1340 1333 1342 1390 1340 1340 1350 Assuming that the strengths of the steel wire using the existing and new process are approximately normal. a) Is there evidence that the steel manufacturing company should use the existing process to make the steel wires. Use the probability of Type I error at 0 01 Assume that the standard devjation đoes not change.

An investigation of the properties of bricks used to line aluminum smelter pots was published in an article. Six different commercial bricks were evaluated. The life span of a smelter pot depends on the porosity of the brick lining (the less porosity, the longer the life span); consequently, the researchers measured the apparent porosity of each brick specimen, as well as the mean pore diameter of each brick. See the table. Apparent Porosity (y). Mean Pore Diameter (x). Click the icon to view the table. Data table Mean Pore Diameter Apparent Porosity (%) (micrometers) Brick Interpret the y-intercept of the line. Choose the correct answer below. 18.7 12.0 В 18.3 9.8 O A. The y-intercept is Bo- This value has no meaning because 0 is not in the observed range of the independent variable mean pore diameter. 16.3 7.3 6.9 5.4 O B. The y-intercept is Bo: For each unit increase in mean pore diameter, the mean porosity is estimated to increase by B0- 17.2 10.9 O C. There is not enough…
