Suppose we are testing the null hypothesis Ho: μ = 20 against Ha: μ ≠ 20. Suppose our population is Normal with standard deviation 6. A random sample of nine (9) observations are drawn from the population, and we find the sample mean of these observations is 17. The P-value is closest to

[Hint: firstly find the test statistic, then use an appropriate statistical table and consider the nature of the alternative hypothesis]
