Which distribution should you use for this problem? Explain your choice. The Student's t-distribution for 80 degrees of freedom should be used because we do not know the population standard deviation. The standard normal distribution should be used because the population standard deviation is known. The standard normal distribution should be used because the sample standard deviation is known. The Student's t-distribution for 81 degrees of freedom should be used because the sample standard deviation is known.
