Write a formulation for the 9th term of the sequence below 5, 15, 45, 135

a ^5 = 405

I dont really know the answer

answer: 95%ci is mean +/1 1.96*sigma/sqrt(n); interval is +/- 1.96*1.95/sqrt(13)=1.06, which is the margin of error.

the interval is 5.35+/- 1.06 or (4.29, 6.41)  

without looking at the choices, this means that the true value for the patient is highly likely to be in this interval. the true value, of course, is either in the interval or isn't, which is a 0-100% probability question, not . one can be highly confident, however, that the true value is in this interval.  

stated another way, if there were 100 cis constructed, 95 of them would contain the true value. we just don't know which 95 of them.  

with the choices above, the second from the bottom "there is a 95% chance " would be the answer.  

for the sample size, 1.96*1.95/sqrt(n) < =1.10

1.1 sqrt(n)> =3.822, sqrt (n) > =3.474, n> =12.07 or 13
