Suppose the lifespan of a wombat is normally distributed. You believe that the mean is greater than 16. You collect a sample of size n = 43 wombats and compute the average to be 17.1 years. It is known that the population standard deviation is σ = 6 years. What is the P-value and what decision should he make at a 5% significance level?
