Chapter 1.3, Problem 103E

(a)

To determine

To calculate: The linear model for the JetBlue net income J as a function of the Southwest Airlines net income S using the data of $2012$ and $2014$, if the table representing the net incomes (in millions of dollars) of various airlines during the period $2010-2014$ is as follows,

Year	$2010$	$2011$	$2012$	$2013$	$2014$
Southwest Airlines	$450$	$200$	$400$	$750$	$900$
JetBlue Airways	$100$	$90$	$130$	$170$	$400$
Alaska Air Group	$250$	$250$	$300$	$500$	$600$

(b)

To determine

To calculate: The net income of the JetBlue Airways in $2010$ on the basis of net income of Southwest Airlines in $2010$ when the table representing the net incomes (in millions of dollars) of various airlines during the period $2010-2014$ is as follows,

Year	$2010$	$2011$	$2012$	$2013$	$2014$
Southwest Airlines	$450$	$200$	$400$	$750$	$900$
JetBlue Airways	$100$	$90$	$130$	$170$	$400$
Alaska Air Group	$250$	$250$	$300$	$500$	$600$

(c)

To determine

The units of measurement of the slope and also interpret about the net incomes of JetBlue Airways and Southwest Airlines from the slope which is calculated in part (a).
