The table to the right gives the number of mistakes made by 8 data entry clerks who enter medical data from Entered Errors D case report forms. These forms are submitted by doctors who participate in studies of the performance of 7,749 36 drugs for treating various illnesses. The column Entered indicates the number of values entered, and the 5,706 34 column Errors gives the number of coding errors that were detected among these. Complete parts a through 6,280 15 e. 1,529 20 3,363 36 1,640 26 4,239 18 3,803 56 (a) Make a scatterplot for these data. Which did you choose for the response and which for the explanatory variable? Describe any patterns. Choose the correct graph below. Entered Which did you choose for the response and which for the explanatory variable? 0 The explanatory variable is Errors and the response is Entered. O The explanatory variable is Entered and the response is Errors. Describe any patterns. Choose the correct answer below. 0 A. There is a positive linear pattern. 0 B. There is a negative then positive curve. O c. There is little or no pattern. 0 D. There is a negative linear pattern. (b) Find the correlation r for these data. r=D (Type an integer or decimal rounded to three decimal places as needed.) I'llI- L __I__J. .._. .. ___...__.f_\\ {0) Suppose we were to record the counts in the table in hundreds, so 7,749 became 77.49. How would the correlation change? Why? 0 A. The correlation would be multiplied by 100 because the values are being divided by 100. O B. The correlation would be divided by 10, the square root of 100, because the values are being divided by 100. O c. The correlation would be divided by 100 because the values are being divided by 100. O D. There would be no change. (d) Write a sentence that interprets the value of this correlation. Choose the correct answer below. 0 A. The correlation indicates a very strong association between the number of data values entered and the number of errors. 0 B. The correlation indicates a very weak association between the number of data values entered and the number of errors. 0 C. The correlation indicates no association between the number of data values entered and the number of errors. (e) One analyst concluded, "It is clear from this correlation that clerks who enter more values make more mistakes. Evidently they become tired as they enter more values." Explain Miy this explanation is not an appropriate conclusion. O A. There's little association between the number entered and the number of errors. 0 B. The association between the number entered and the number of errors switches from a negative association to a positive association. 0 6. There's a large association between the number entered and the number of errors. O D. This is a correct explanation
