<span>Answer:
Calculating the t test statistic
t = (xbar - mu)/(s/sqrt(n))
t = (4.40-4.66)/(0.28/sqrt(6))
t = -2.27452618972722
t = -2.275
The t test statistic is approximately -2.275</span>
Answer: 378
-------------------------------------

Work Shown:
f(x) = x^2 - 3x
f(x) = ( x )^2 - 3*( x )
f(-18) = ( -18 )^2 - 3*( -18 ) ... replace every x with -18; now use PEMDAS
f(-18) = 324 - 3*( -18 )
f(-18) = 324 + 54
f(-18) = 378
