The scores on an exam are normally distributed, with a mean of 85 and a standard deviation of 5. What percent of the scores are from 85 to 95?

basically it shows how much of the data is within so many standard deviations of the means. Your mean is 85, that's 0 deviations away. The standard deviation is 5, so 95 would be 2 standard deviations away. Does that make sense?
uh well im not really sure what a standard deviation is to be honest
it's a measure of how spread out the data is. If it's small, then a lot of the scores would be really close to the mean. If it's big, then the data is more spread out
so the data in this case would be spread out by 5
sort of. the graph up above only works for normal distributions, meaning most of the data is falls within 5 points of the mean. Specifically 68%

If we were to label the graph with numbers from your problem 85 would go in the middle because that's the mean
since the standard deviation is 5, you can add labels to the right increasing by 5 and labels to the left decreasing by 5
make sense?
so to the the percentage from 85 to 95 you just add 34 and 13?
right
cool i got it! thank you so much!!
you're welcome
