Transcribed Image Text:While shopping for an air conditione, a buyer bonsulted the following table giving a machine's BTUS and the square footage ( that it would cool
t' (x)
BTUS (y) 5100 5400 6350 6700 7275 7825 8300 8550 9750 9900
150 175 230 250 285315 350 360 435 | 450
(a) Find a linear model for the data. (b) Use the results from part (a) to find the number of BTUS required to cool rooms of 360 ft, 435 r, and 450 (c) Suppose
a room measures 215 Use the results from part (a) to decide how many BTUS it requires if the air conditioners are available only with the BTU cholces in the
table, which is the best choice?
(a) Find a linear model for the data Find the least-aquares regression ine Once you have found the line in ynix+b form, input the values of m and b into the
appropriate boxes below
A linear model for the data is y
