O det(A) = (-3)(-6) – (1)(6)
O det(A) = (-3)(-6) + (1)(6)
O det(A) = (1)(6)-(-3)(-6)
O det(A) = (-3)(-6) + (-1)(-6)

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).
