Null Hypothesis: Ho – the type of community and section of newspaper are independent
Alternative hypothesis: H1 – the type of community and section of newspaper are dependent
Determining test statistics
χ2test = Σ[(f0 – fe)2/fe]
Where,
f0 = observed frequency of the category
fe = expected frequency of the category
The expected frequency of the category is calculated as follows:
fe = (∑rf0)(∑cf0)/(n)
∑rf0 = total observed frequency of respective row
∑cf0 = total observed frequency of respective column
n = total number of observation = 420
Expected frequency for city resident and national news subscriber category = (90)(216)/(420) = 46.29
Similarly expected frequencies for the remaining category are as follows:

Contribution of category to Chisquare test is calculated as follows:
Contribution = (f0 – fe)2/fe
For City and national news category the contribution is calculated as follows:
Contribution = (32 – 46.29)2/(46.29) = 4.41
Similarly, contributions of other categories are obtained as follows:

test statistics
χ2test = Σ[(f0 – fe)2/fe]
Value of test statistics = χ2test = 47.32
Critical value
Degree of freedom = (r – 1)(c – 1) = (3 – 1)(3 – 1) = 4
Significance level = 1 – 0.95 = 0.05
From table of Chisquare, χ2critical = 9.488
Using the critical value approach, the decision rule is to reject the null hypothesis if χ2test >= χ2critical
Since, χ2test (47.32) >= χ2critical (9.488), we reject null hypothesis that the type of community and the section of the newspaper subscriber reads are independent at a = 0.05.
From table, χ2test = 60.44 and degree of freedom = 4, pvalue < 0.005
Since pvalue < a (0.05), reject null hypothesis.
Thus, there is sufficient data to conclude that there is relationship between the type of community and the section of the newspaper subscriber reads at 95% confidence level.
