Question

Find the mean and standard deviation for the data set of the number of elevator stops for several rides. Round your answers to the nearest tenth. Enter your answers separated by commas; example: 2.3, 7.5.
{0, 3, 1, 1, 0, 5, 1, 0, 3, 0}

anonymous · Answer

How would you find the mean of this data set?

anonymous · Answer

i calculated the mean to be 1.4 @cormacpaynee

anonymous · Answer

Total Numbers:	10
Mean (Average):	1.4
Standard deviation: 1.727	
Variance(Standard deviation): 2.93~	
Population Standard deviation: 1.62481
Variance(Population Standard deviation): 2.64

anonymous · Answer

would you mind just checking that

anonymous · Answer

Okay great! Now all you have to do is use the standard deviation formula:
$$\sqrt{\sum_{i = 1}^{N}\frac{ (x_{i} - \mu)^{2} }{ N - 1}}$$

anonymous · Answer

So since this is just a sample and not the population, you would ignore the population standard deviation given, and use just the plain standard deviation of 1.727

anonymous · Answer

hmm its weird when i put that into the school website is says im wrong ):

anonymous · Answer

im putting in 1.4,1.727

anonymous · Answer

1.4,1.7 didn't work either

anonymous · Answer

im gonna cry iv been working on this all day ;-; lol

anonymous · Answer

I ran it on my calculator and got Sx = 1.7127

anonymous · Answer

Try that number ^

kk 1 sec

anonymous · Answer

nope still no dice

anonymous · Answer

im not sure what im doing wrong

anonymous · Answer

I'm not sure either, 1.4, 1.7127 should be the answer for the mean and standard deviation

anonymous · Answer

And you said 1.4, 1.7 did not work? They want it to the nearest tenth.

anonymous · Answer

yea it didn't work either

anonymous · Answer

That's really odd, because that should be the answer

anonymous · Answer

Maybe try 1.4, 1.6 just to give the other standard deviation a shot
