Answer:
i would say it is false not true
Answer:
it is quite simple it's just that you need to substitute the input in place of x
eg:if the input is 2 then 2(3(2)+4) = 20 and 20 is the output
Use a z-test where z=(xbar-mean)/sigma/sqrt(n)
The denominator is the SE and is 1.6/sqrt(30)=0.292
z=-0.5/0.292 and .9/.292 or between -1.71 and 3.08
that probability is 0.9553.
