Please help with part F which I got wrong answers: P-value of the sample statistic rounded to 4 decimal places: I thought it’s 0.0801 but the system said it’s wrong and Part G- Conclusion Fail to reject HO at a= ? I put 0.01 but that’s wrong too. Please help me with this question. Picture#2 Thank you!!!!

Transcribed Image Text:Nassau Community College uses thousands of fluorescent light bulbs each year. The brand of bulb it currently uses has a mean life of 848 hours with a population standard deviation of 72 hours. A manufacturer claims that its new brand of bulbs, which cost the same as the brand the college currently uses, has a mean life of more than 848 hours. The college has decided to purchase the new brand if, when tested, the test evidence supports the manufacturer's claim at the 1% significance level. Suppose 49 bulbs were tested and the mean life was found to be 866. Complete the steps of a hypothesis test below, and then answer the question, "should the college purchase the new brand of light bulbs?" (a) State the hypotheses: Họ: The population mean light bulb life is equal to 848 Vo hours. Symbols: O o.-20 0 µ1 - 0 Pz-z0H po 848 H: The population mean o light bulb life is more than 848 O hours. 848 (b) The correct symbol for the mean of the sampling distribution is: OPi - P2 Op Or O I2 - I1 Ox O P-22 Op (c) The value for the mean of the sampling distribution is: 848 (d) Choose the correct distribution: OT-Distribution O Chi-Square Distribution
