Given:
estimate = 140
actual = 152
Percent of error = |(estimate - actual)/actual| * 100%
% of error = |140 - 152| / 152 * 100%
= |-12|/152 * 100%
= 0.0789 x 100%
% of error = 7.89% rounded to the nearest tenth 7.9%
Increasing the frequency of observations in the tails of a distribution will increase the standard deviation because the data points are added once observations are made. In this case, the data points may be attributed to more error that increases the separation between data points.
Option 1 is the Answer.
For explanation, then please check the attached image.

There are 360 degrees so divide 360 by 20 and get 18 degrees
