Unlike most glass houses, Root appears to have assigned a new number for each bottle type it produced. The heel numbers probably begin with 1 (but not on Coke bottles!)

### Number of Theoretical Plates (N) - Agilent

Theoretical plate numbers are only valid for a specific set of conditions. Specifically, isothermal temperature conditions are required because temperature programs result in highly inflated, inaccurate plate numbers. Also, the retention factor (k) of the test solute used to calculate plate numbers should be greater than 5.

statistic (the farther from the mean), the smaller the p-value. When the p-value is very small, researchers can say they have strong evidence that the null hypothesis is false. This is because if the p-value is very small, it means that the probability of obtaining a score that is so extreme or even higher is very small.

### Guide to Interpreting

The standard deviation is a measure of variability of scores around the mean. Large numbers for the standard deviation indicate that the data are very spread out (i.e., there is a lot of variability). Conversely, a very small standard deviation would indicate that most of the data are very similar to the mean (i.e., less variability).

### Powers of 10 & Scientific Notation

In all of the physical sciences, we encounter many numbers that are so large or small that it would be exceedingly cumbersome to write them with dozens of trailing or leading zeroes. Since our number system is base-10 (based on powers of 10), it is far more convenient to write very large and very small numbers in a special exponential

At least for small numbers, there is a way to ﬁnd the binary digits for a given number ( i.e., given in base 10) by repeatedly dividing by 2. For very small numbers, we can more or less do it by eye. Say for the number twenty one, we can realise that it is more than 16 = 24 and not as big as 32 = 25. In fact

test. The test itself is very rapid. On a manually operated unit, a Rockwell test takes only five to ten seconds, depending upon the size and hardness of the specimen, as well as pre-load and dwell time. Also, the indentation is extremely small and usually does not need to be removed by machining, making this a non-destructive test. A
