Blood-alcohol level (mg per 100 mL-")
Figure Histogram of blood-alcohol measurements.
The figure shows the probabilities of a single experimental result, with a standard deviation
of 2.0, falling within unit ranges about a mean value of 80.
Calculate, using the data in figure, the probabilities that a single experimental result will fll
within the following ranges (in mg per 100 mL):
i) 80-81
ii) 81-83
iii) >80
iv) 78-82 (i.e. 80 ±1 standard deviation)
v) 76-84 (i.e. 80 ±2 standard deviations)
vi) 74-86 (i.e. 80 ± 3 standard deviations)
vii) 72-88 (i.e. 80 14 standard deviations)
viii)<86
