In: Statistics and Probability
For each of the following situations give the degrees of freedom and an appropriate bound on the P-value (give the exact value if you have software available) for the χ2 statistic for testing the null hypothesis of no association between the row and column variables.
(a) A 2 by 2 table with χ2 = 0.76.
df = | |
P-value = |
(b) A 4 by 4 table with χ2 = 18.67.
df = | |
P-value = |
(c) A 2 by 8 table with χ2 = 23.33.
df = | |
P-value = |
(d) A 5 by 3 table with χ2 = 12.88.
df = | |
P-value = |
