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.

OK. I will show you how to do the first one for Indiana. Then you do the rest of them by copying what I did. Here we go:
693 / 6,000,000 =0.0001155 =1.16 x 10^-4 - Deaths per capita
[1.16 x 10^-4] x 100,000 =11.6 - Deaths per 100,000 people.

You have the population of Illinois as 2.4 million!!. The actual population of Illinois was approx. 12.8 million in 2017.
