As a result of monitoring the sodium content of 155grams of shellfish, data(unit: mg) were obtained asshown in the table. If you collect 20 more cartons ofshellfish samples, the average sodium content in allshellfish (including original data) was 600.8 mg andthe standard deviation was 0.955 mg in the test forsymmetry using 0.05 p.m.ln conclusion, there is 600mg of sodium in the filtration, and if the actual averagesodium content in the filtration is 600.5 mg, find out.Power of test (correctly decided probability)600.0601.8599.4601.3600.3599.7600.1600.7602.4602.3600.2601.4601.1600.6601.8599.7
