The percentage of homes in Jacksonville are less than 1,760 square feet is 84%.
Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (raw score - mean)/standard deviation
Given that:
Mean = 1390 ft², standard deviation = 370 ft²
For x < 1760:
z = (1760 - 1390) / 370 = 1
P(x < 1760) = P(z < 1) = 84%
