Step-by-step explanation:
The compound interest formula is equal to
where
A is the Final Investment Value (future value)
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above

Answer:
a) 0.85
b) 0.0160
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a saple of size n, the mean of the sampling distribution of sample means is p and the standard deviation is
In this problem, we have that:
(a) Calculate the mean of the sampling distribution of the sample proportion.
By the Central Limit Theorem, 0.85
(b) Calculate the standard deviation of the sampling distribution of the sample proportion. (Round your answer to four decimal places.)
