Consider the following hypotheses tests involving the χ2-distribution.
(a) Determine the p-value for Ho:
P(1) = P(2) = P(3) = P(4) =
0.25, with χ2 = 5.85. (Give your answer bounds
exactly.)
< p <
(b) Determine the p-value for Ho:
P(I) = 0.25, P(II) = 0.40, P(III) =
0.35, with χ2 = 5.34. (Give your answer bounds
exactly.)
< p <
a) Under H0, the test statistic follows a chi square distribution with 4 -1 = 3 df.
p-value
So, 0.10 < p-value < 0.15
b) Under H0, the test statistic follows a chi square distribution with 3 -1 = 2 df.
p-value
So, 0.05 < p-value < 0.10
