Question 736512: (Posted in the wrong place the first time sorry!)
For the questions use this data

a. Find the mean, median, mode and standard deviation of the data. Round to the nearest hundredth if necessary.
b. Determine whether the data in the table appears to be positively skewed, negatively skewed, or normally distributed. Explain.
I found the mean to be 374.88 the median-356. I don't believe there is a mode because there are no repeating numbers. I am a little confused on how to find the standard variation. I think the graph might be normally distributed but I am not sure because the numbers are all over the place if you use them in the order they are given.
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! You are correct with the mean and median.
There is no mode.
Using my TI-84 I get std = 260.5
-------
I think you could find the std using a stat site online.
Cheers,
