Document Summary
You may have one page of notes during the exam. Calculators are permitted: (30%) the following data shows the weight measured for 14 us nickels in grams. A couple of sums have been calculated for your convenience (each data point is called. = __________________________: (10%) calculate a 95% confidence interval for the sample mean. The factors involved in the experiment were the power applied to the cathode, the pressure in the reaction chamber, the spacing between the anode and cathode, and the flow of the reactant gas c f . The response variable is selectivity of the process for silicon nitride over polysilicon. The data is shown on the 3rd and 4th excel printouts. List the better of the two mathematical models found in these two regressions.
