A clinic administerstwo drugs to two groups of randomly assigned patients to cure the same disease
A clinic administerstwo drugs to two groups of randomly assigned patients to cure the same disease: 70 patients received Drug I and 80 patients received Drug II. The following table gives the information about the numbers of patients cured and those not cured by each of these two drugs.
To perform a chi-square test of homogeneity for this contingency table at the 10% significance level, what is the critical value of chi-square?
5.991
4.605
3.841
2.706
Homework Answers
Ans:
degrees of freedom=(2-1)*(2-1)=1
significance level=0.1
critical chi square value=CHIINV(0.1,1)=2.706
Correct option is 2.706

Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person randomly selected 100 checks and recorded the cents portions of those checks. The table below lists those cents portions categorized according to the ated values Use a 0.10 significance level to test the claim that the four categories are equally likely. The person expected that many checks for whole dollar amounts would result in...
