3) Identify those letters whose Cls do not overlap with any the CIs of any of the other letters. (For example the CI [0.042, 0.052] overlaps with [0.050, 0.060] because the upper bound of the first CI is greater than the lower bound of the second CI.) List the letters with the non- overlapping Cis and specify how many such letters there are. (6 points) 4) The previous analysis could be useful if our goal was to decipher an encrypted message, where each letter is scrambled (for example, each \"a\" might become a \"g\
