Chi-square statistic=6.5
(a) What are the degrees of freedom for the test?
(b) What is the p-value?
Round your answer to five decimal places.
(c) What is the conclusion, using a 5% significance level?
Reject H0: There is evidence that the assumed proportions are wrong.
Reject H0: There is evidence to support the assumed proportions.
Do not reject H0: The assumed proportions appear to be wrong.
Do not reject H0: The assumed proportions seem correct.
