Answer:
20.27
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation
Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
This is s when . So
So the correct answer is:
20.27
Since 6 is greater than 5 you input it into the last equation!
2•(6^2) -7
2•(36) -7
72 -7
65
The answer is 65!
The saving plan balance is $3,677.53.
Given that,
- The no of months is 18.
- The annual percentage rate is 3% so the monthly rate percentage is 0.25%.
- And, the monthly payment is $200.
Based on the above information, the following formula should be used:
FVA = PMT× [(1+r)^n - 1] ÷ r
= $200 × [(1+ 0.0025)^18 - 1] ÷ 0.0025
= $3,677.53
Therefore we can conclude that the saving plan balance is $3,677.53.
