Question 1162674: The average rent in a city is $1,500 per month with a standard deviation of $200. Assume rent follows the normal distribution. [You may find it useful to reference the z table.]
a. What percentage of rents are between $1,300 and $1,700? (Round your answer to the nearest whole percent.)
b. What percentage of rents are less than $1,300? (Round your answer to 1 decimal place.)
c. What percentage of rents are greater than $1,900? (Round your answer to 1 decimal place.)

You can put this solution on YOUR website! z=(x-mean)/sd
a is looking for a z between -1 and +1, which is 0.6827
b is looking for z less than -1, which is 0.1587
c is looking for a z greater than 2 which is 0.0228
