Members of the Ontario Field Ornithologists (OFO) observe birds at various locations within the province to see how many different species of bird they can spot.Suppose that 21 members have reported spotting the following number of species in 2014.The lower stem contains leaves with the digits 0-4 and the upper stem contains leaves with digits 5-9.

11 ∣7\mid 7∣7 = 117 birds
A) The distribution of the number of birds spotted by OFO members in 2014 is skewed right,with a centre at around 125 birds.There are several high outliers,with two members spotting 158 birds and another spotting 178.With the exception of these outliers,most members saw between 102 and 139 birds.
B) The distribution of the number of birds spotted by OFO members in 2014 is skewed right,with a centre at around 111 birds.There are several high outliers,with two members spotting 158 birds and another spotting 178.With the exception of these outliers,most members saw between 102 and 139 birds.

Skewed
A distribution that is not symmetric and has one tail longer than the other, indicating that the data are not evenly distributed around the mean.
Ontario Bird Count
An event or initiative focused on counting bird species and populations within the province of Ontario to track avian biodiversity and population trends.
Outliers
Data points that differ significantly from other observations, which can occur due to variability in the measurement or possibly indicate experimental error.

Final Answer :
B
Explanation :
The stem-and-leaf plot shows a skewed right distribution with a long tail of high outliers. The center is around 111 birds, and the majority of members saw between 102 and 139 birds, with two high outliers at 158 and 178 birds. Therefore, option B accurately describes the distribution.
