Answer:
The answer to the question is
The percent of the distribution is less than m + d is 84 %
Step-by-step explanation:
To solve the question we list out the variables
Percentage of distribution between m +d and m - d = 68 %
Therefore percentage that are outside the range of m + d and m - d = 32 %
For symmetry to be maintained, of the 32 % that are outside the range of m + d and m - d, 16 % are on either side of the range m + d to m - d
That is 16 % < (m-d) ↔ (m+d)< 16% total range = 100 %
Therefore the proportion of the range lesser than m+d = 100 - 16 or 84 %
