B. What other estimate gives the same percent error? Explain your reasoning.
To get the same percent error, the amount of error needs to be
Because your estimate was
people below the actual attendance, an estimate of
the actual attendance will give the same percent error. Therefore, the other estimate that gives the same percent error is an estimate of
people.

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).
