answer. (b) 37.60 (c) 0.0130 (d) 13000 2 S (e) 1.3400 2. Perform the indicated operations to the correct number of significant figures using the rules for significant figure (a) 37.60 x 1.23 462 (b) 0.75 6.7 8.975 (c) 0.0000089 x 6500.00 (in scientific notation) 106 Questions 3-6. Three students named Abe, Barb, and Cal make measurements (in m) of the length of a table. Find the means, a using the data given: Student L L2 L3 LA Abe 1.4717 1.4711 1.4722 1.4715 111.4716 0.00046 0.000 Barb 1.4753 1.4759 1.4756 1.4749 Cal 1.4719 1.4723 1.4727 1.4705 1.4754 0,00043 0.0002 14719 0.00096 0005 Only one significant figure is kept in the standard error a, and this determines the number of significant figures in the mean. The actual length of the table is 1.4715 m. error 3. Find the percentage diffrnees in length measured by three students. 4. State how one can measure the accuracy of a measurement. Apply your idea to the measurements of three students above and state which of the students has the most accurate measurement. Why is that your conclusion? 5. State the characteristics of data that indicate a systematic error. Do any of the three students have data that suggest the possibility of a systematic error? If so, state which students it is, and state how the data indicate your conclusion. 6. Which student has the best measurement considering both accuracy and precision? State clearly what the characteristics are of the student's data on which your answer is based.
