Explanation / Answer

For

(a) X2 = 7.456

which is less than the critical chi-square value X2critical = 24.789. So,

We do not reject the null hypothesis because the standardized test statistic is not under rejection region. Option A is correct.

(b)  

X2 =0

which is less than the critical chi-square value X2critical = 24.789. So,

We do not reject the null hypothesis because the standardized test statistic is not under rejection region. Option A is correct.

(c)

X2 = 1.769

which is less than the critical chi-square value X2critical = 24.789. So,

We do not reject the null hypothesis because the standardized test statistic is not under rejection region. Option D is correct.

(d)

X2 = 24.721

which is less than the critical chi-square value X2critical = 24.789. So,

We do not reject the null hypothesis because the standardized test statistic is not under rejection region. Option A is correct.
