Past examples of heritage minutes include Lucy Maud Montgomery, Viola Desmond, Terry Fox, and Sir John A. Macdonald. Historica Canada polls random samples of Canadians to gage knowledge level and interest in potential topics. One recent poll investigated Canadians' knowledge of Autumn Peltier. Autumn Peltier, a member of the Wiikwemkoong First Nation, has been advocating for clean drinking water in Canadian First Nations communities and elsewhere since the age of 8. Now at 15 years of age, she holds the title of Chief Water Commissioner for the Anishinabek Nation and has spoken about clean water at a UN conference. In June 2020, a random sample of 1001 Canadians aged 18+ were asked about their age group (grouped by generation) and whether they knew that 15-year-old Autumn Peltier was named "chief water commissioner" by the Anishinabek Nation in 2019 and has been fighting for water rights since the age of 8. Is there an association between knowledge of Autumn Peltier and generation (Gen Z, Millennial, Gen X, Boomer)? The results are presented in the table below. (Source: Ipsos Canada. (2020). While Half Of Canadians Know Their Country Contributed To Eradicating Polio, Most Don't Know The Face On Their $10 Bill.] Knowledge of Autumn Peltier Generation Yes No Gen Z 40 78 Millennial 65 187 Gen X 56 224 Boomer 64 287 Activate Windows Go to Settings to activate Windows.

1, explain why the appropriate test to use is a chi-squared test of independence. clearly refer to the relevant population(s) and categorical variable(s) in your answer.

b, state the hypothesis (Ho and Ha), making sure to refer to your population(s) and variable(s)

Answer 1

1. Here the whole population of 18+ Canadians are classified into two atribute, knowledge of Autumn Peltier and generations which are the categorical variables. We can calculate the proportion of memebers falling in each class of those attributes . Also, any of the class does not contain frequency which is less than 5% of the total members. So, to test whether there is association between knowledge of Autumn Peltier and generations or not, thye chi squared test of independence is appropriate .

b) The null hyouthesis :-

$H_0:$ The knowledge of Autumn Peltier and generations are independent for the 18+ Canadians .

The alternative hypothesis :-

$H_1:$ The knowledge of Autumn Peltier and generations are associated for the 18+ Canadians .
