CAn someone tell me if I have done this question correctly and what else I need to do

3. A famous formula that can be used to roughly estimate the Blood Alcohol Concentration

(BAC) percentage is theWidmark formulagiven as

where

Ounces’ is the liquid ounces of alcohol consumed.ADR’ is the alcohol distribution ratio. This is equal to 0.73 for males and 0.66 for females.Weight’ is the weight (kg) of individual whose BAC is to be estimated.Hours’ is the time in hours since the first drink.

(a) Suppose we wish to estimate the BAC% of a male who weighs 80kg and who has

consumed 2.7 liquid ounces of alcohol over the past 2.5 hours. Write an R script

file (make sure you submit your commands when handing in your assignment) that

i. Assigns appropriate values to the R objects Ounces, Weight, ADR and Hours

that will be used to estimate the BAC% for this individual.

ii. Uses these R objects and theWidmark formulato estimate the BAC%.

What is the estimated BAC% for this person?

> ((2.7*5.3*0.73)/(2.2/80))-0.015*2.5

[1] 379.8280

(b) Now suppose that this person has consumed the same amount of alcohol over 3

hours. By changing just the value you assigned to Hours in your script, what is

the estimated BAC% now?

> ((2.7*5.3*0.73)/(2.2/80))-0.015*3

[1] 379.8205
