Run BELL-SHAPED CURVE for a sample size of 250, and complete the following tables. Note: ERROR = % OBSERVED − % PREDICTED.

a. Compute the lower and the upper limits of the interval for the uniform popula-tion with k = 3, using the following formula: LOWER LIMIT = MEAN − K*STANDARD DEVIATION = _____________ UPPER LIMIT = MEAN + K*STANDARD DEVIATION = ______________

b. Which population produced a sample that is approximated best by the Normal Bell-Shaped Curve? _____________________________________________

c. Run BELL-SHAPED CURVE program again for sample size 500 to test your conclusions. Comment on the results.
