Rents in $$ Frequency
300 but less than 400 113
400 but less than 500 85

700 but less than 800 4
What percentage of the apartments rented for less than $600?

Answer 1

Answer:

92%

Step-by-step explanation:

The percentage of apartments rented for less than $600 is given by the sum of all of the apartments in the 300 to 400, 400 to 500 and 500 to 600 intervals divided by the total number of apartments sampled (250).

$P(X<600) = \frac{113+85+32}{250} \\\\P(X<600) =0.92 =92\%$

92% of the apartments rented for less than $600.
