A student wanted to determine the percentage of sulfate in Q07. seven different unknown solid samples; he used two different methods, namely the gravimetric method, and the titration with 0.05 M barium chloride employing an adsorption indicator to reveal the end point of the titration. He obtained the following results as shown in the table below: %Sulfate (Gravimetric Method) Sample # %Sulfate (Titration with adsorption indictor Method) 63.53 64.00 2. 67.29 75.21 53.98 50.69 70.05 68.15 3 75.98 4 55.01 51.53 71.52 58.16 56.32 Question: Use the student t-test to check if the two methods vielded results that are significantly different from each other at 95%% confidence level (HA) or if the difference can be explained by the random error (Ho).
