Q1) For Normal distribution X~N(3, 4). Use SPSS to make a normal probability table. In first column, input numbers from -6 to +12 in increment of 0.5, then compute cumulative probabilities for these numbers in second column. Then create a histogram illustrating data distribution. Using generated Normal probability table, determine probability of Pr(X<=5).
