Question

To test the hypothesis that the population mean mu=15.8, a sample size n=29 yields a sample mean 16.805 and sample standard deviation 2.738. Calculate the P-value and choose the correct conclusion.

Options:

The P-value 0.229 is not significant and so does not strongly suggest that mu>15.8.

The P-value 0.229 is significant and so strongly suggests that mu>15.8.

The P-value 0.026 is not significant and so does not strongly suggest that mu>15.8.

The P-value 0.026 is significant and so strongly suggests that mu>15.8.

The P-value 0.009 is not significant and so does not strongly suggest that mu>15.8.

The P-value 0.009 is significant and so strongly suggests that mu>15.8.

The P-value 0.020 is not significant and so does not strongly suggest that mu>15.8

The P-value 0.020 is significant and so strongly suggests that mu>15.8.

The P-value 0.029 is not significant and so does not strongly suggest that mu>15.8.

The P-value 0.029 is significant and so strongly suggests that mu>15.8.

Answer 1

Answer : The P value is 0.029 is not significant and son does not strongly suggest that mu >15.8
