Question

a) The table below shows the populations of several states (in millions) and the number of motor vehicle deaths in each. Complete the table by computing the number of motor vehicle deaths per capita (number of deaths per person) for each of the states. Express these in scientific notation rounded correctly to the hundredths place. Also, convert these values to the number of deaths 'Per 100,000 People' in standard notation rounded correctly to the tenths place. (Source: US Census Bureau ) State MV Deaths Population (million) Per capita (in SN) Per 100,000 People Indiana 693 6 1.155 x 10^-7 0.0001155 Illinois 911 12.4 Ohio 1021 11.35 8.996 x 10^-5 0.0 Michigan 871 9.9 Alaska 64 0.63 b) Which state has the worst rate? c) Which state has the best rate?

Answer 1

A.) The completed table is in the attached picture.
      Per capita calculation steps
      Step 1: Per capita = MV Deaths / Population
      Step 2: Convert to Scientific notation
      Step 3: Round-off to hundredths (2nd digit from the right of decimal place)
      Per 100K people calculation steps
      Step 1: Per 100K people = MV Deaths / Population * 100, 000
      Step 2: Round-off to tenths (1st digit from the right of decimal place)

B) I used my completed table (attached picture)
    Therefore, Indiana has the worst rate with 11.6 MV Deaths per 100K People

C) Again, I used my completed table (attached picture)
    Therefore, Illinois has the best rate with 7.3 MV Deaths per 100K People
