Answer:
a) 22.94 psi
b) 
Step-by-step explanation:
a)The pressure at which will trigger a warning is
31 - 31*0.26 = 22.94 psi
b) The probability that that the TPMS will trigger warning at 22.94 psi, given that tire pressure has a normal distribution with average of 31 psi and standard deviation of 2 psi

where x = 22.94, 


Given:
The inequality is:

To find:
The inequality after isolating the y-term.
Solution:
We have,

On simplification, we get


Subtracting 2 from both sides of the above inequality, we get


Therefore, the required inequality is
