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.
