MATH530 Applied Statistics Question 1 Identify whether the variable in the information below is qualitative or quantitative. Government agencies carefully monitor water quality and its effect on wetlands (Reference: Envi ronment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the co ncentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish an d wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen conce ntration (milligrams of nitrogen per liter of water) was determined for each sample. Question options: quantitative qualitative qualitative as well as quantitative neither qualitative nor quantitative Information does not have any variable

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) 1334 1330 13 10 1340 Existing 1365 1286 1320 1333 1300 1350 New 1300 1310 1340 1342 1390 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 deviation does not change.

A. A scatterplot. B. A bar chart. C. A stem-and-leaf display. D. Side-by-side boxplots. 4 Mr. Prudence read about the study results and concluded from there that hospitals should adopt computerized automation of notes and records because it increases patientsâ chance of survival. Which of the following is a correct statement about Mr. Prudenceâs conclusion? A. It is a valid conclusion because the study was based on a very large number of patients. B. It is a valid conclusion because the study results showed that hospitals which use computerized systems have a lower patient death rate. C. It is an invalid conclusion because this study does not necessarily prove a causal relationship between the use of ||| computerized system and hospital mortality. D. Both A)…
