t test

Step-by-step explanation:

given that a researcher is interested in the whether the number of times each week people exercise differs between Canadians and British people

To test this, she asks 1000 people (500 Canadians and 500 British)

Here two groups are being compared

500 people taken from each group is sufficiently large and assuming random sampling, we can say that these 500 represent the population they belong to.

For comparing two groups to find whether there is significant difference in the number of times each week people exercise differs between Canadians and British people, appropriate test would be a t test.

Since population std deviations for the two samples are now known we use sample std deviation and hence do t test for comparison of two population means.
