Exercise 4: We wanted to know if the composition of the populations of four canadian provinces are similar in terms of school level people over 25 years of age. This variable is broken down into 5 modalities (A=no diploma, B=high school diploma, C=Baccalaureate,

D= Mastery, E=Ph. D). We therefore selected a random sample of 50 people over the age of 25 in each of these provinces and obtained

The following results:

	School level
A	B	C	D	E
Quebec	7	21	6	10	6
Ontario	5	26	8	6	5
Colombie-Britannique	5	19	11	11	4
Alberta	5	18	15	5	7

(A) Formulate the hypotheses to be tested.

(B) What is such a hypothesis test called?

(C) Take your test and conclude with a significance threshold of 5%.
