Write an equation for a circle with center at (-9,5) and diameter = 24. a. (x + 9)2 + (y – 5)2 = 144
C. (x-9)2 + (+ 5)2 = 144
b. (x+ 9)2 + (1 - 5)2 = 576
d. (x-9)2 + + 5)2 = 576

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).
