please help me with this Question
the original Question is in German language but I translate it to English I will also provide some example may help you understand the Question
Exercise 6 (analysis and mean values) in an analytical laboratory, the sugar content of a product is determined using different measuring methods. In order to be able to compare the different mean values, they hay_e____tg be calculated. The reference examination delivers the following values: Mass 5,2 4,5 5,2 4,7 5,8 4,7 4,7 5,2 5,8 4,7 in mg a) Calculate the average mass as number mean, mass mean and centrifuge mean. b) Calculate the distribution width (polydispersity index PDi). c) Sketch the distribution in a suitable graphic representation and mark the numerical mean, mass mean and centrifuge mean in each case. Example with answer : may help you Mean values - Example Steinhaufen: 20 Steine 1 kg 50 Steine 2 kg 70 Steine 3 kg 40 Steine 4 kg 10 Steine 5 kg 5 Steine 6 kg Task: Calculate number averages, mass averages and centrifuge means_as well as PDI Zahlenmittel Massenmittel Zentrifugenmittel M - Zn; .
