1.35 p) a) Oc with the same analysis method, the protein percentage in a food sample is three times b) A car hits a pedestrian and runs away. Determine if there is a 95% given level difference between the Ce method in the paint on the sample taken from the pedestrian's clothing, ) If there is a difference at the 95% confidence level, which method is better than the others. Obtained results are given below. 2.87 4.92 3.28 4.18 3.92 Method I 2.17 Method 11: 2.99 Method I I1: 4.40 Determine 3.51 b A car hits a pedestrian and runs away. The Cr found in b on the sample taken from the pedestrian's clothing and the Cr in the paint taken from the accused vehicle are determined by a spectroscopic method. When the results are compared with each other, is there any reason to suspect the vehicle that was involved in the accident as the culprit? 6035% Cr was found from the data accumulated from many analyzes. Apply the 95% and 99% confidence levels as criteria. Color from clothes % Cr: 4.0, 4.6 Paint from car % Cr: 4.5, 5.3, 5.5, 5.0, 4.9
