I believe your question is to find a range going from the mean to a z-value on the standard normal distribution that corresponds to 17% of the area. A normal distribution goes from values of minus infinity to positive infinity. A standard normal distribution has a mean of 0 and an standard deviation of 1. It is usually best if you draw a diagram, in this case a bell shape curve with mean = 0. The area to the left of the mean is 50% of the total area. We find a z value that corresponds to 67% (50% + 17%) of the area to the left of this value. This can be done either with a lookup table or a spreadsheet program. I prefer excel, +norminv(0.67) = 0.44. The problem could also be worded to find the area going from a z-value to the mean. In this case, we must find a z-value that corrsponds to 33% (50-17). Using Excel, I calculate +norminv(0.33) = -0.44.
The value is 0.3055
z = ±0.44

how to figure out the difference between the greatest value and the least vaule for 2.5.12.7.9
The value is 0.3055
z value=0.44
z = ±0.44
A z score of .5 corresponds to 19% of the data between the mean and z. P( 0 < z < .5) = .19
The answer is 47
It i the smallest value in the data set and corresponds to the value of the left-most end of the whisker. Unless there were outliers, in which case it will be an "X" to the left of the left-whisker.
It is 84.3%
Percent deviation formula is very useful in determining how accurate the data collected by research really is. Percent Deviation = (student data-lab data) / lab data then multiplied by 100 Note: If the percent deviation is a negative number that means the student data is lower than the lab value.
RANGE IS the diffrence between the greatest value data and the least value of data
Percent deviation is the accepted value minus the observed value divide by the observed value multiplied by 100. The formula is useful in deciding how correct the data is that is collected by students.
THe 75th percentile
the difference between the highest value and the lowest value in your data
