1. Assuming the distribution of SPHRS1 is normal, calculate (using the formula) the number of people who worked 30 hours or less. (4 points)2.Use the Frequencies procedure to construct a table of the percentage of cases at each value of hours worked. Compare the theoretical calculation (obtained in the previous step "e") with the actual distribution in the sample. What percentage of people in the sample work 30 hours or less? Is this value close to what you calculated? If there is a discrepancy, why might that be so? (4 Points)
