A well-designed and safe workplace environment can contribute greatly to raised productivity. It is especially significant that workers not be asked to lift objects that are to heavy. Assume a researcher for large manufacturing company wishes to find out if the average age weight lifted per lift for all workers at company exceeds 25 pounds. A random sample of 80 workers is obtained and a t-test is performed by the researcher. Suppose the observed t-test value was 1.2 with a p-value of .117.
A) Identify the population of interest. Also identify a random variable whose probability distribution describes the research population
B) Identify the parameter of interest to the researcher.
C) Give Ho and Ha of interest to the researcher
D) Define the p-value.
E) Draw the appropriate picture for the p-value.
F) State the appropriate conclusion
G) Define the power for this test.
H) Give the assumption required for this test
