The information given in the above problem can be represented with the following notations as follows:

Sample size = n = 1000
Here = 0.55
P0 = 0.5
Q0 = 0.5
The is the value of the sample of 1000 Canadians response about the cananian adult should stand is given as 55%
So 55% of total 1000 is the number of Canadian adult should stand = (55/100)*1000 = 550
So, X is the number of Canadian adult should stand = 550

Null hypothesis:
The ...
