Some doctors find this highly improbable because Hepatitis B vaccines take more than one dose. They administered this vaccine to 9 volunteers until the volunteers developed Immunity. It tool: an average of 3 doses with a standard deviation of 1.6 for the volunteers to develop immunity. Find the test statistic and its p -value rounded off to two {2} decimal places. Test Statistic value = Blank 1 P-Value = Blank 2%
