Answer:
109.33
Step-by-step explanation:
given that the population has a distribution with a mean of 110 and a standard deviation of 8
Sample size n = 40
Std error of sample mean = std dev/square root of sample size
= 
From std normal distribution table we find that 30th percentile for Z is
-0.5244
Corresponding x score =
30th percentile = 109.33663
=109.33

So, since we have a cubic equation with 4 terms, the first thing we should try is factoring by grouping, so:

Now that we've factored our equation, we can use ZPP and break it up:

So, our solutions are:
