What percentage of scores would lie between 55 and 95 according to Chebychev's Theorem? 2. What percentage of scores would lie between 55 and 95 if the distribution belongs to the family of normal distributions? (This is the empirical rule) Assume that the above distribution is approximately normal. 3. What is the probability that a person chosen at random will make 100 ofabove on the test?...
