Need only a handwritten solution only (not a typed one).

Question 2 To test the hypothesis that the population standard deviation sigma-3.0, a sample size n=20 yields a sample standard deviation 1.801. Calculate the P-value and choose the correct conclusion. Your answer: The P-value 0.142 is not significant and so does not strongly suggest that sigma<3.0. The P-value 0.142 is significant and so strongly suggests that sigma<3.0. The P-value 0.373 is not significant and so does not strongly suggest that sigma<3.0. The P-value 0.373 is significant and so strongly suggests that sigma<3.0. The P-value 0.018 is not significant and so does not strongly suggest that sigma<3.0. The P-value 0.018 is significant and so strongly suggests that sigma<3.0. The P-value 0.005 is not significant and so does not strongly suggest that sigma<3.0. The P-value 0.005 is significant and so strongly suggests that sigma<3.0. The P-value 0.240 is not significant and so does not strongly suggest that sigma<3.0. The P-value 0.240 is significant and so strongly suggests that sigma<3.0.
