Step-by-step explanation:
Given that IQ mean is 100 and std dev = 12 for normal adults
Std error =
i.e. sample size should be atleast 97
The required sample size is 97.
This is reasonable as this is greater than 30
Yes. This number of IQ test scores is a fairly large number.
It does not say simple or compound interest.
Simple interest is rarely used these days, so assume compound.
Use the standard formula:
future value = present value*(1+rate/n)^(nt)
n=number of times interest is compounded per year (=1)
t=number of years
Plugging values,
200=100(1.09)^t
1.09^t = 2
take log
t(log(1.09))=log 2
t=log(2)/log(1.09)=0.6931/0.08618=8.04 years.
