This director, who released the movie "Alien" in 1979 is still making hit movies today, most notably his recent success, "Prometheus".

These percentages roughly represent the percent of the data values that fall within one, two, and three standard deviations from the mean of a normal distribution.
What is 68–95–99.7%?
300
A normal distribution has a mean of 10 and a standard deviation of 1. The percentage of data values that fall between the values of 8 and 12 is this.
What is 95%?
300
In a standard normal distribution, we use z-scores to find percentages of the data that fall within a certain range. One z-score represents this amount of standard deviations from the mean.
What is one?

What is 18 and 30?
400
A data value that is an element of a non-standard distribution is called this.
What is a raw score?
400
The percentage of the data of a distribution that lies between a z–score of 0 and –1.38 is this.
