GMAT PREP Questions

[ahaaxyz]

Hello,

I have some queries from GMATPrep software that GMAC ppl send.
I gave the test and got 730. I got some questions in Quant section wrong which I feel I did right.I would appreciate any help that I can get from here.
I have my GMAT on 8th. So here goes my first question -

1)70,75,80,85,90,105,105,130,130,130.

The list above shows time in secs that it took for 10 school children to run 400 m . If Standard deviation of 10 running times is 22.4 secs, how many of 10 running times are more than 1 standard deviation below the mean of 10 running times.

Answer choices 1)1 2)2 3)3 4)4 5)5

My answer 5. Answer Given is 2 and there is no explanation provided.

Please help me out if possible.

Thanks a lot...
