1. Sum the counts in the 55+ age column. Then explain why the sum is not the same as the entry for this column in the total row.
2. Find the percent of people in each group who did not complete high school. Compare these percents. State briefly what the data shows.
To answer the questions:
1. Summing the counts in the 55+ age column gives us a total of 56,008. However, this sum is not the same as the entry for this column in the total row, which is 81,435. The reason for this discrepancy is that the total row represents the total number of people across all age groups, whereas the sum of the 55+ age column only includes the counts within that specific age group. So the total row includes people from all age groups, including those who completed high school, college, or did not complete high school, whereas the 55+ age column only includes people aged 55 and above.
2. To find the percent of people in each group who did not complete high school, we need to divide the count for "Did not complete high school" in each age group by the total count for that specific age group, and then multiply by 100 to get the percentage.
For the age group 25 to 34, the percent is (4,474 / 37,786) * 100 ≈ 11.84%.
For the age group 35 to 54, the percent is (9,155 / 81,435) * 100 ≈ 11.24%.
For the age group 55+, the percent is (14,224 / 56,008) * 100 ≈ 25.39%.
Comparing these percentages, we can see that the percent of people who did not complete high school is highest in the 55+ age group (25.39%) compared to the other age groups. This indicates that there may be a higher proportion of individuals in the older age group who did not complete high school compared to the younger age groups.
