Which equation represents a line that passes through (5, 1) and has a slope of 1/2? Oy-5= 1/2(x-1)
oy- į = 5(x-1)
oy-1 = 1/2(x–5)
oy-1 = 5(x-1/2)

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).
