Given the explicit formula u(n) = -15 + 20n, where u(1) = 5, find the recursive formula for u(n). a. u(1) = 5 and u(n + 1) = u(n) + 20, for n = 1, 2, 3, . . b. u(1) = 5 and u(n + 1) = 5u(n) + 20, for n = 1, 2, 3, . . c. u(1) = 5 and u(n + 1) = u(n) + 5, for n = 1, 2, 3, . . d. u(1) = 5 and u(n + 1) = 20u(n) + 5, for n = 1, 2, 3, . .

Im literally having a mental breakdown

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).
