To test the hypothesis that the population standard deviation sigma=15.7, a sample size n=24 yields a sample standard deviation 10.525. Calculate the P-value and choose the correct conclusion. The P-value 0.011 is not significant and so does not strongly suggest that sigma<15.7. The P-value 0.011 is significant and so strongly suggests that sigma<15.7. The P-value 0.346 is not significant and so does not strongly suggest that sigma<15.7. The P-value 0.346 is significant and so strongly suggests that sigma<15.7. The P-value 0.021 is not significant and so does not strongly suggest that sigma<15.7. The P-value 0.021 is significant and so strongly suggests that sigma<15.7. The P-value 0.005 is not significant and so does not strongly suggest that sigma<15.7. The P-value 0.005 is significant and so strongly suggests that sigma<15.7. The P-value 0.280 is not significant and so does not strongly suggest that sigma<15.7. The P-value 0.280 is significant and so strongly suggests that sigma<15.7.
