When we need to calculate the resultant value of them.......
1. A. medium
2. B. matter
3. B. straight lines
im sorry i couldnt help for number 4 but hope this helps
We make use of a one-sample t-test for a population mean.
One-sample t-test for a population mean
Option B
<h3> Sample mean and Sample standard deviation</h3>
A Sample Standard Deviation is the root-mean square of the data minus the sample mean,
The sample mean is is the mean of the randomly selected sample
Therefore, For a data or sample where we have no information on population standard deviation and here only one sample group is compared, we make use of a one-sample t-test for a population mean
A one-sample t-test for a population mean

Option 4 ( R2 and R3 ) is the correct answer.
Explanation:
- In the below given diagram, we can see a circuit diagram that has four resistors such as R1, R2, R3, and R4.
- The opening of the circuit is noted as "a" and the ending is noted as "b".
- By observing the above diagram, we can clearly see that R2 and R3 are the pair of resistors that are connected in a parallel manner.
- Where all the other resistors such as R1 and R4 are neither connected in parallel nor in series.
Hence we can conclude that Resistor R2 and R3 are the ones that are connected in parallel.
