Answer 1

a) null and alternative hypotheses.

D. H0 : The row and column classifications are independent.

Ha : The row and column classifications are dependent.

b)

A. Test statistic = $\sum \frac{(n_f - E_f)^2}{E_f}$

We are given level of significance α = 0.01

Degrees of freedom (df) = (r-1)(c-1)           r is numer of rows and c is number of column.

df = ( 2-1)(3-1) = 2

Therefore critical value $1596212301491_blob.png$   _(0.01,1) = 9.21034 -------- ( From chi square table )

Rejection region :

A. $1596212301491_blob.png$ > 9.21034
