Chi squared = $\frac{(O_{i} - E_{i} )^{2} }{E_{i} }$

Where:

$O_{i}$ = observed value
$E_{i}$ = expected value.

Kryger [21]

Answer:

This is an exponential growth problem.

The growth rate is 4% (0.04).

The time is 10 years (10 years from 2005 to 2015)

A = P(1+i)t

A = amount spent in 2015

P = amount spent in 2005

i = interest rate expressed as a decimal

t = # years

A = 500(1.04)10

A = 500(1.480244)

A = 740.122 ==> 740 billion
