NEED HELP I have no clue how to do this and need an answer by the end of today! I need to label and display my new polynomial identity. Prove that it is true through an algebraic proof identifying each step. And lastly demonstrate that my polynomial identity works on numerical relationships.

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).

Find the value of x. give reasons to justify your solutions! c ∈ ae
