A statistician is conducting a hypothesis test to determine if the average lifespan of a certain species of bird is equal to 10 years. The null hypothesis is that the average lifespan is equal to 10 years. The sample mean is calculated to be 9.8 years with a standard deviation of 1.5 years. If a significance level of 0.05 is used, what is the p-value of the hypothesis test?
