Ages 15 up to 20 20 up to 25 25 up to 30 30 up to 35 35 up to 40 40 up to 45 Relative Frequency 0.10 0.25 0.28 0.24 0.11 0.02 i. Write the values of the cumulative relative frequency distribution. ii. What percent of the women were at least 25 but less than 35 years old? iii. Assume the relative frequency distribution is based on a sample of 2,000 women. How many women were less than 30 years old?

Compute the R² using the following information. What does this number mean? Wage = 4.43 +0.61Edu + e n = 1089, SST = 37211.6, SSE 37211.6, SSE 19848.2 R² = = = 0.4666. 46.66% of the variation in wage can be explained by education. R² = 0.5334. 53.34% of the variation in wage can be explained by education. R² = 0.61.61% of the variation in wage can be - explained by education. R² = 0.3043. 30.43% of the variation in wage can be explained by education.

A group of 10 people have the following annual incomes: $55,000, $30,000, $15,000, $20,000, $35,000, $80,000, $40,000, $45,000, $30,000, $50,000. Complete the table.   Income Quintile Share of Income $15,000 Bottom   $20,000 $30,000 2nd   $30,000 $35,000 3rd   $40,000 $45,000 4th   $50,000 $55,000 Top   $80,000   If $4000 is taxed from the top earner and transferred to the lowest earner, would that increase or decrease the share of income held by the top quintile? Would this transfer increase or decrease the share of income held by the bottom quintile? Would this have any effect on the 2nd quintile? The 3rd? The 4th? Would this transfer increase, decrease, or have no effect on income inequality in this group? Redistributing income from the highest earner to the lowest one would reduce the utility of the top earner and increase the utility of the lowest earner. But what would happen to the overall utility of the…
