A cryptocurrency company wants to estimate the mean value of bitcoin in its customers' accounts (measured in dollars). They know that the population standard deviation of bitcoin amounts across accounts is $700. They take a random sample of 20 accounts that yields a sample mean of $2,700. The company would like to test whether the data provide sufficient evidence that the mean value of bitcoin per customer is less than $3,000. What is the p-value?
