Arsenic is toxic to humans, and people can be exposed to it through contaminated drinking water, food, dust, and soil. Scientists have devised an interesting new way to measure a person's level of arsenic poisoning: by examining toenail clippings. In a recent study,1 scientists measured the level of arsenic (in mg/kg) in toenail clippings of eight people who lived near a former arsenic mine in Great Britain. The following levels were recorded: 0.8, 1.9, 2.7, 3.4, 3.9, 7.1, 11.9, 26.0 Do you expect the mean or the median of these toenail arsenic levels to be larger?

The mean, because the outlier values are above the mean.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is given by the sum of all values of the data-set divided by the number of values.

Median:

The median of a data-set is the value that separates the lower 50% from the upper 50% of the sorted set.

0.8, 1.9, 2.7, 3.4, 3.9, 7.1, 11.9, 26.0

Finding the median, since it is easier.

8 values, the median is the mean between the 4th and the 5th values. (3.4+3.9)/2 = 3.65

The values below the median are quite close to it, while those above it are considerably more distant, considered outliers, which means that we should expect the mean to be larger than the median.

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
