For example, in the 1930s Widmark measured alcohol and blood by mass, and thus reported his concentrations in units of g/kg or mg/g, weight alcohol per weight blood. Blood is denser than water and 1 mL of blood has a mass of approximately 1.055 grams, thus a mass-volume BAC of 1 g/L corresponds to a mass-mass BAC of 0.948 mg/g.
In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
Latvia: 0.02% for drivers with less than two years of experience and 0.05% for those with more than two years of experience. [105] Liechtenstein: 0.08% [106] Lithuania: Zero for taxi, truck, bus, motorcycle drivers, drivers with less than two years of experience and 0.04% for those with more than two years of experience [81]
Lower-end snow ratios below the 10 to 1 rule of thumb are found in situations where temperatures are warmer and less ideal for snow either aloft or near the ground.
In a significance test, the null hypothesis is rejected if the p-value is less than or equal to a predefined threshold value , which is referred to as the alpha level or significance level. α {\displaystyle \alpha } is not derived from the data, but rather is set by the researcher before examining the data.
In engineering, precision is often taken as three times Standard Deviation of measurements taken, representing the range that 99.73% of measurements can occur within. [8] For example, an ergonomist measuring the human body can be confident that 99.73% of their extracted measurements fall within ± 0.7 cm - if using the GRYPHON processing system ...
The election's outcome was not known for more than a month after voting ended because of the time required to count and recount Florida's ballots. Between 7:50 p.m. and 8:00 p.m. EST on November 7, just before the polls closed in the largely Republican Florida panhandle, which is in the Central time zone, all major television news networks ...
The second one, which was much larger than the first one, produced at least 108 tornadoes, pushing the month to well above average. With 127 confirmed tornadoes, it was the second most active December on record, behind only 2021 (which had 227 tornadoes).
