Ineed an answer asap! an experiment is broken up into two parts. in the first part of the experiment a penny is tossed in the air. if the coin lands on heads, then the coin is flipped a second time. if the coin lands on tails, then a six-sided die is rolled. what is the probability of getting exactly one head?

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).
