When you say âPower Rangersâ this is what 95% of people my age will immediately think of. Power Rangers Zeo (1996). I have some vague recollection of this, but remember thinking it wasnât as cool as the original. Power Rangers Turbo (1997). Pretty sure I had at least one of these action figures because my parents didnât know the difference between the series.
A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. Areas of the normal distribution are often represented by tables of the standard normal distribution. A portion of a table of the standard normal distribution is shown in Table 1. Table 1.
The standard deviation is an especially useful measure of variability when the distribution is normal or approximately normal (see Chapter on Normal Distributions) because the proportion of the distribution within a given number of standard deviations from the mean can be calculated.
