Do this question on your own paper.  You can type “see paper” in the box when finished.For each situation below, set up the hypotheses and identify the claim. Then indicate if the test is a left-tail, right-tail, or two-tail test. Also indicate if it will be a -test or a -test.a) A manufacturer claims that the mean lifetime of its light bulbs is 1000 hours. A homeowner selects 25 bulbs and finds the mean lifetime to be 980 hours with a standard deviation of 80 hours.b) A fast-food outlet claims that the mean waiting time in line is less than 3.4 minutes. A random sample of 60 customers has a mean of 3.3 minutes with a population standard deviation of 0.6 minutes.c) A local bakery claims that no more than 15% of their loaves of sourdough bread have an internal temperature below 200 degrees Fahrenheit when they leave the oven. A consumer advocacy group suspects that the actual proportion of under-baked loaves is higher than the bakery’s claim. To investigate, the group randomly sampled 120 loaves of sourdough bread and found that 24 of them had an internal temperature below 200 degrees Fahrenheit.
