If you have samples of n 1 equals 22 and n 2 equals 20, in performing the pooled-variance t test, you have 40 degrees of freedom.
The t-test method is a method where we analyze two sets of data which both these data are independent of each other. This pooled variance test helps us in getting the overall variance in both these different sample sets when we know that both the sample sets are almost equal.
To calculate degrees of freedom, we have the formula
df = n1 +n2 -2
According to the question, n1= 22 and n2= 20
Therefore, degree of freedom= 22 +20 -2 = 40
Hence, degree of freedom is 40.

Technological innovations like desalination allowed people living in areas without adequate freshwater sources to adapt to their environment because desalination allows people to live, grow food, and mine natural resources in regions without many freshwater resources.
Desalination is that the process of removing salts or other minerals and contaminants from seawater, brackish water, and wastewater effluent and it's an increasingly common solution to get water for human consumption and for domestic/industrial utilization.
Desalination uses reverse osmosis technology to remove water molecules from seawater.
Desalination could be a process that takes away mineral elements from saline water.
The process is named "desalination", and it's being employed more and more round the world to grant people with needed freshwater.
