Use the Frequencies procedure to construct a table of percentage of cases at each value of AGE. Compare the theoretical calculation in C. with the actual distribution of age in the sample. What percentage of people in the sample are 25 years old or less? Is this value close to what you calculated? Why might there be discrepancy? The answer to C is Given data Mean: 46.88, Standard deviation: 1:1.142, N=1491. If X is the age of the chosen person in the sample which is normally distributed with mean and standard deviation, then the standard normal of person age is Z: 1.28. The probability of random chosen person to be 25 years of age (or) less an sample. As there are N=1491 peOpIe in the data so, the number of people expected to have age less than 25 is N: N x P(Z
