<em>Additional comment</em>
It is helpful to memorize the squares of integers 1-20 and the cubes of integers 1-10. Being able to recognize these numbers can save you a lot of time on problems like this.
7/10 / 3/1
7/10 x 1/3
7/30

Answer:
30.17 cm
Step-by-step explanation:
area of a circular disc=π*r^2
derivative of area=2*π*r
maximum error= derivative * error in radius
i.e . 2*π*r*0.2
Answer:
X[bar]= 115
Step-by-step explanation:
Hello!
Every Confidence interval to estimate the population mean are constructed following the structure:
"Estimator" ± margin of error"
Wich means that the intervals are centered around the sample mean. To know the value of the sample mean you have to make the following calculation:
![X[bar]= \frac{Upper bond + Low bond}{2}](https://tex.z-dn.net/?f=X%5Bbar%5D%3D%20%5Cfrac%7BUpper%20bond%20%2B%20Low%20bond%7D%7B2%7D)
![X[bar]= \frac{115.6+114.4}{2}](https://tex.z-dn.net/?f=X%5Bbar%5D%3D%20%5Cfrac%7B115.6%2B114.4%7D%7B2%7D)
= 115
Since both intervals were calculated with the information of the same sample, you can choose either to calculate the sample mean.
I hope it helps!
