Answer:


Step-by-step explanation:
Given


Solving (a); Point estimate of mean
To do this, we simply calculate the sample mean




Solving (b); Point estimate of standard deviation
To do this, we simply calculate the sample standard deviation





<em>Note that: The sample mean and the sample standard deviation are the best point estimators for the mean and the standard deviation, respectively.</em>
<em>Hence, the need to solve for sample mean and sample standard deviation</em>
In mathematics, mean average means to take the sum of all the numbers and divide the sum by the number of elements in the set.
Add up the numbers.
<span>21 + 23 + 25 + 25 + 26 + 28 + 28 + 28 + 31 + 33 = 268
Divide by the number of elements in the set. Which is 10.
268 / 10 = 26.8
So, the answer to this question is 26.8</span>

Step-by-step explanation:
Assuming Jerry calculates that if he makes a deposit of $6 each month at an APR of 4.8%, then at the end of two years the correct balance will be: $158.5
First step is to determine Jerry total deposit
over the two years
Total deposit = 24×$5
Total deposit= $144
Now let determine what the correct balance will be at end of two years
Using this formula
Maximum Amount=Principal (1+r)^t
<em>Where</em>:
Principal=$144
r=4.8%/12 = 0.4% or 0.004
t=24 months
Let plug in the formula
Maximum Balance = $144 (1.004)^24
Maximum Balance = $158.5
Based on the above calculation both Jerry $100 and Benny $163 balance are eliminated or rule out because the correct balance after two years is $158.5
Inconclusion Assuming Jerry calculates that if he makes a deposit of $6 each month at an APR of 4.8%, then at the end of two years the correct balance will be: $158.5
