The normal white cell count is usually between 4 × 10 9 /L and 1.1 × 10 10 /L. In the US, this is usually expressed as 4,000 to 11,000 white blood cells per microliter of blood. [7] White blood cells make up approximately 1% of the total blood volume in a healthy adult, [8] making them substantially less numerous than the red blood cells at ...
The reference range provided by the particular lab that performed the testing should always be used to interpret the results. [3] Also, some healthy people may have values outside of the "normal" range provided by any lab. [citation needed] Modern analyzers use ion-selective electrodes which give a normal anion gap as <11 mEq/L. Therefore ...
The median age is the index that divides the entire population into two numerically equal age groups, one younger than that age and the other older than that age. It is the only index associated with the age distribution of a population. [1]
Share of adults that are obese, 1975 to 2016. Obesity is common in the United States and is a major health issue associated with numerous diseases, specifically an increased risk of certain types of cancer, coronary artery disease, type 2 diabetes, stroke, and cardiovascular disease, as well as significant increases in early mortality and economic costs.

Violent crime rate per 100k population by state (2023) [1] This is a list of U.S. states and territories by violent crime rate. It is typically expressed in units of incidents per 100,000 individuals per year; thus, a violent crime rate of 300 (per 100,000 inhabitants) in a population of 100,000 would mean 300 incidents of violent crime per year in that entire population, or 0.3% out of the total.
For sufficiently large values of λ, (say λ >1000), the normal distribution with mean λ and variance λ (standard deviation ) is an excellent approximation to the Poisson distribution. If λ is greater than about 10, then the normal distribution is a good approximation if an appropriate continuity correction is performed, i.e., if P( X ≤ x ...
Since 10 meters can frequently open up to propagate globally, most 10-meter repeaters use a CTCSS sub-audible access tone. 16 kHz-wide signals with 5 kHz deviation is normal in this band. 8 kHz-wide signals with 2.5 kHz deviation can also be found. 2.5kHz deviation is mandated by FCC rules below 29.0 MHz.
