Transcribed Image Text:

To test the hypothesis that the population standard deviation sigma-20.1, a sample size n=5 yields a sample standard deviation 15.688. Calculate the P-value and choose the correct conclusion. Your answer: O The P-value 0.324 is not significant and so does not strongly suggest that sigma<20.1. O The P-value 0.324 is significant and so strongly suggests that sigma-20.1. ○ The P-value 0.009 is not significant and so does not strongly suggest that sigma<20.1. The P-value 0.009 is significant and so strongly suggests that sigma<20.1. 00 The P-value 0.344 is not significant and so does not strongly suggest that sigma<20.1. The P-value 0.344 is significant and so strongly suggests that sigma-20.1. O The P-value 0.315 is not significant and so does not strongly suggest that sigma<20.1. The P-value 0.315 is significant and so strongly suggests that sigma<20.1. ○ The P-value 0.271 is not significant and so does not strongly suggest that sigma<20.1. O The P-value 0.271 is significant and so strongly suggests that sigma<20.1.
