The NHTSA estimates that <u>85 %</u> of the 11,510 drivers with a BAC of .01 or higher who were involved in fatal crashes had BAC levels at or above .08.
<u>Explanation:</u>
The survey conducted by the “National Highway Traffic Safety Administration (NHTSA)” says that the driver with high BAC levels is the main cause for the fatal crashes.
The amount of alcohol mixed with the blood of a person is identified to know the blood alcohol concentration (BAC) level. The BAC level of the person is determined by taking into account the amount of alcohol consumed by the person, person’s weight, gender, genetics and drinking pattern. Increase in BAC level may leads to side effects and impairments.
The best way to illustrate the relative frequency distribution is a percentage or a proportion.
For example, imagine that in the survey conducted above 80 people where interviewed and 35 were democrat, 24 republican, 12 libertarian, and 9 chose another party.
- Absolut frequencies would be the number of responses for each option: 35, 24, 12 and 9.
- Relative frequency (democrats) = 35/80 = 0.4375= 43,75 % of the participants
- Relative frequency (republicans)= 24/80= 0.3 = 30% of the participants
- Relative frequency (libertarians)= 12/80= 0.15 = 15% of the participants
- Relative frequency (others)= 9/80= 0.1125 = 11,25 % of the participants
