The Air Quality Index, or AQI, measures how polluted the air is in your city and assigns a number based on the quality of the air.
Over 100 is "Unhealthy".
The following quadratic regression equation gives us an estimate of n, which is the number of days the AQI exceeded 100 a
particular year. We will use this equation to estimate the number of days the AQI was over 100 in the year 1995.
n = 1.7612 - 13.32+ + 41.00
(Let t represent the number of years since 1990. Therefore, t = 0 corresponds to the year 1990. For the estimate of n, round to the
nearest whole day.)
18 days
b. 24 days
182 days
d. 72 days
a
C.
