Thread: Need help with a basic statistics question

1. Need help with a basic statistics question

The mean price of new homes from a sample of houses is 155,000 with a standard deviation of 15,000. The data is bell shaped distribution . Between what two prices do 95% of the houses fall?

2. Do you know the significance of 95%? If you have sample data that is normally distributed than 95% of the data would be within two standard deviations from the mean. Can you figure out the prices now?

3. I am confused as to what steps I need to take to figure this out.

4. $\mu = 155000,\sigma= 15000$

95% of values will fall between $\mu - 2\sigma

Go get em!

5. Thanks!!!
