Consider a six faced die whose i-th face is marked with z dots, i = 1, 2,...,6. In a single random throw of the die, let pi denote the probability that the obtained upper face has i dots, i = 1, 2,...,6. The die is rolled 240 times independently and the following result is obtained
| Face observed | 1 | 2 | 3 | 4 | 5 | 6 |
| Frequency | 40 | 55 | 40 | 25 | 35 | 45 |
Suppose we want to test H0 : \(\rm p_i=\frac{1}{6}\) for i = 1, 2,...,6; against H1 : pi ≠ \(\frac{1}{6}\) for at least one i;i = 1, 2,...,6. It is given that \(\rm χ_{5; 0.05}^2\) = 11.07, \(\rm χ_{6; 0.05}^2\) = 12.59, \(\rm χ_{5; 0.01}^2\) = 15.09, \(\rm χ_{6; 0.01}^2\) = 16.81. Based on the asymptotic goodness of fit χ2 test for testing H0 against H1, which of the following statements are true?
1
H0 is rejected at 5% level of significance
2
H0 is rejected at 1% level of significance
3
H0 Is not rejected at 5% level of significance
4
Observed value of the test statistic is 12.5
