Answer:
Average growth= 11.20 feet
Step-by-step explanation:
<u>First, we need to calculate the total growth during those 312 years:</u>
<u></u>
Total growth= 3,512 - 18
Total growth= 3,494 feet

Answer:
And we have a sample size of n =81. We want to estimate the standard error of the sampling distribution 
and for this case we know that the distribution is given by:
And the standard error would be:
And replacing we got:
Step-by-step explanation:
For this case we know the population deviation given by:
