Suspect you've made a mistake in your calculations.
Looking at the Normal curve, the area under it between the mean and 3.09 standard deviations is [approx] 0.4990, ie the probability that the data could exceed 3.09 standard deviations from the mean is 2 x (0.5-0.4990) = 0.002 = 0.2% [using a half-tail table], ie it is quite unlikely that a data point is much further away from the mean than the tables' limit of 3.09.
Beyond 3[.09] standard deviations away from the mean, the area under the curve changes very little in the first 4 dp, so [most] tables are going to not be of much help anyway - when 4 standard deviations away are reached, it is almost all the distribution and rounds to 1.
So if you are looking at a point greater than 3 standard deviations away from the mean it is either a very unusual event that has caused it, or (more likely) you've made a mistake in your calculations.
Because in case grouped frequency distribution table we are sending all i.e mixed frequencies at a time with diff bandwidth wheras in case of regular table we are sending each signal at a time.
In a frequency distribution table, there are usually five parts/columns (12th grade statistics):class, frequency, mid-point, relative frequency, and cumulative frequency.
1.555 With 88% confidence, there is 6% (0.06) in either tail of the standard Normal distribution. Table C will not help here. Using Table A the correct z* is about halfway between 1.55 and 1.56. According to technology, z*=1.555
A frequency distribution of numerical data where the raw data is not grouped.
A left join gets all records from the left linked table. If you have selected columns from the right linked table withouth related records, the columns will be NULL. The normal join gets all records from one table that have related records in a second table.
standard normal is for a lot of data, a t distribution is more appropriate for smaller samples, extrapolating to a larger set.
A distribution table would be primarily used in the field of statistics and probability. Collecting and interpreting data is much easier when compiled in this format.
The z-score table is the cumulative distribution for the Standard Normal Distribution. In real life very many random variables can be modelled, at least approximately, by the Normal (or Gaussian) distribution. It will have its own mean and variance but the Z transform converts it into a standard Normal distribution (mean = 0, variance = 1). The Z-distribution is then used to make statistical inferences about the data. However, there is no simple analytical method to calculate the values of the distribution function. So, it has been done and tabulated for easy reference.
A normal distribution simply enables you to convert your values, which are in some measurement unit, to normal deviates. Normal deviates (i.e. z-scores) allow you to use the table of normal values to compute probabilities under the normal curve.

Oxygen has an atomic number of 8, not 6. The number above an element on the Periodic Table generally is the atomic number. Carbon has an atomic number of 6.
For statistical tests based on (Student's) t-distribution you use the t-table. This is appropriate for small sample sizes - up to around 30. For larger samples (or degrees of freedom), the t-distribution becomes very close to the Standard Normal distribution so you use the z-tables.
Yes, they provide the normal distribution z table on the P1 exam, at least on the computer exam. I'm not sure about the paper and pencil exam.
The number listed above the symbol of an element on the periodic table is the element's atomic number.
Mass number
Random numbers (or random deviates) are numbers chosen totally by chance, but also conform to a certain distribution. The most common distribution is the uniform distribution. If I say that a number is chosen totally by chance between 1 and 100, and there is equal chance that every number between 1 and 100 can be chosen, then this is a uniformly distributed random number. If I list these generated numbers in a table, then this is a random number table. A program like Excel can easily generate uniform random numbers from 0 to 1, by entering +rand() into a column in the spreadsheet. To calculate a new table, press F9.
