Final Examination Math 311 Name Schwiegerling May 15, 2019 Read the directions and each question carefully. For each question, be sure to include Ho, Ha, a claim, a numerical calculation, a diagram, and a concluding sentence. ALL calculated results should be to 2 decimal places! 1a) A sprinkler alarm system in an office complex is designed to activate when the room temperature reaches at most 128 F. To test this claim you randomly select 33 alarm systems and find that the mean activation temperature is 130.4° F with a population standard deviation of 6.4° F. At α 0.01 is there enough evidence to reject the manufacturer's claim? İb) If n were increased to 4s in this problem, w hat would be your concluding sentence.
