c)90th percentile = 82.6 kgThis demonstrates to us that 90% of individuals surveyed weigh less than 82.6 kg, and thus 10% ofindividuals surveyed weigh greater than 82.6 kg.d)Main features of the graphThe majority of the individuals have lower levels of total mercury detected in their hair samples,therefore displaying a strong right skew. The graph is asymmetrical and unimodal, with the mode beingat the 1.80-3.58 mg/g interval. Here, we can assume that most individuals within this sample have beenrevealed to relatively low levels of mercury.The outliers in this sample are the two individuals with mercury levels greater (between 16.01,17.79mg/g) than the rest of the sample. This could be due to these individuals being fishermen who catch andeat fish in bodies of water that have exposure to high levels of mercury, or possibly construction workersthat work in surroundings with high levels of mercury too.e)The mean would not be an appropriate measure of central location, due to the asymmetrical,
