According to the National Association of Realtors, the mean sale price for existing homes in the United States in 2011 was $214,300. Assume that sale prices are normally distributed with a standard deviation of $41,000. Find the percentage of existing homes in 2011 that sold for between $173,300 and $296,300?

82% of the existing homes in 2011 are sold between $173,300 and $296,300.

Step-by-step explanation:

The left side of the mean ⇒ 34% = M-SD, 14% = M-2SD, 2% = M-3SD

The right side of the mean ⇒ 34% = M+SD, 14% = M+2SD, 2% = M+3SD

The percentage of existing homes in 2011 that sold for between $173,300 and $296,300 is 34%+34%+14% = 82%

2 over 5

step-by-step explanation:
