A seamstress is using an old cloth measuring tape marked with units to \( 1 / 8 \) of an inch, but the problem is that the old measuring tape has stretched and always gives a slightly larger measurement. The tape is used to measure the length of a dress pattern and then the same tape is used to measure the width of the same pattern. A length of \( 6 \frac{7}{8} \) inches is measured. a) What can you say about the degree of accuracy of the measurement? b) What can you say about the degree of precision of the measurement?
