Hypotheses for a chi-square goodness-of-fit test are given, along with the sample data and the chi-square statistic.
Hypotheses:
Но : РА 3D 0.7, рв
Ha: Some p; is not as given
: 0.2, Pc = 0.1
Sample Data:
A
В
C
Observed(Expected) | 139(139) 41(40) 19(20)
Chi-square statistic = 0.1
(a) What are the degrees of freedom for the test?
i
(b) What is the p-value?
Round your answer to five decimal places.
p-value =
i
(c) What is the conclusion, using a 5% significance level?
O Reject Ho : There is evidence that the assumed proportions are wrong.
O Do not reject Ho : The assumed proportions appear to be wrong.
O Do not reject Ho : The assumed proportions seem correct.
O Reject Ho : There is evidence to support the assumed proportions.
