1. Monna and co-workers used radioactive isotopes to date sediments from lakes and estuaries.21 To verify this method they analyzed a 20$Po standard known to have an activity of 77.5 decays/min, obtaining the following results. 77.09 75.37 72.42 76.84 77.84 76.69 78.03 74.96 77.54 76.09 81.12 75.75 i. Determine whether there is a significant difference between the mean and the expected value at a = 0.05. Show your calculations and the steps to derive the conclusion.
