Finding percentages with standard deviations
Activity overview:
and it corresponds to the integers in the figure above. In other words, the z-score is the number of standard deviations a data point is above or below the mean. The . p-th percentile. of a distribution is the value such that p percent of the observations fall at or below it. Part 1 – Given x-values, finding percentages. Problem: Too Good ...

How many standard deviations is that? 3.75. Convert Einstein’s IQ score to a z score. (160 – 100)/16 = 3.75. If we consider “usual IQ scores to be those that convert z scores between -2 and 2, is Einstein’s IQ usual or unusual? Unusual. Women’s heights have a mean of 63.6 in. and a standard …

standard deviations from the mean. Example: Here is a dotplot of Kobe Bryant’s point totals for each of the 82 games in the 2008-2009 regular season. The mean of this distribution is 26.8 with a standard deviation of 8.6 points. In what percentage of games did he score within one standard deviation of …

For example, since we know that 99.7% of all our data typically lie within 3 standard deviations of the mean, the odds of seeing an observation more extreme than 3 standard deviations above or below would only be .03% (Which comes from subtracting 99.7% from 100%).

In fact, for any number (or fraction) of standard deviations, we know exactly what percent of the data fall within that number of standard deviations of the mean. For example, consider the normal curve percentages in the table below. Given a number z of standard deviations, the table gives the percent of data values between the mean ( and ((z(.
