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.

With over two million lakes and rivers and 20 per cent of the world’s freshwater, Canada has an incredible abundance of aquatic natural resources. Canadians share a deep historical connection to freshwater; we rely on it for transportation, for resources, for employment, for food and for recreation — swimming, boating, fishing or simply admiring the scenery of a natural lake or wild river.
Unfortunately, many of Canada’s freshwaters are no longer the pristine ecosystems they once were. At CWF, we are working to encourage a better balance between the needs of our society and of the ecosystems that sustain us.

Answers may vary. It suggests the sequential images of film, the medium that made Monroe famous.
Explanation:

The correct answer is We can predict the time between eruptions will be 10.73 minutes and this can be stated with 0.901 probability.
Eruptions do not always produce symmetrical and imposing cones. Volcanic relief has varied shapes and we must analyze the properties of the lava and the conditions of spill occurrence to understand.
