Question
A researcher is interested in investigating whether the military branch a person slgns up for and the person's blood type are dependent. The table below shows the results of a survey. Frequencies of Military Branch and Blood Type A B AB Army Navy Air Force 100 50 42 25 122 62 40 28 115 78 42 28 Marines 125 88 50 23 What can be concluded at the a 0.05 significance level? a. What is the correct statistical test to use? O Homogeneity O Paired t-test O Independence O Goodness-of-Fit b. What are the null and alternative hypotheses? Но: O Blood type and branch of the military are dependent. O The distribution of blood types is not the same for each branch of the military. O The distribution of blood types is the same for each branch of the military. O Blood type and branch of the military are independent. H1 : Ttranch of the military are dependent.

H1: O Blood type and branch of the military are dependent. O The distribution of blood types is not the same for each branch of the military. O The distribution of blood types is the same for each branch of the military. O Blood type and branch of the military are independent. c. The test-statistic for this data = (Please show your answer to three decimal places.) d. The p-value for this sample (Please show your answer to four decimal places.) e. The p-value is Select an answer f. Based on this, we should O fail to reject the null O reject the null O accept the null g. Thus, the final conclusion is... O There is insufficient evidence to conclude that the distribution of blood types is not the same for each branch of the military. O There is insufficient evidence to conclude that blood type and branch of the military are dependent. O There is sufficient evidence to conclude that blood type and branch of the military are dependent. O There is sufficient evidence to conclude that blood type and branch of the military are independent.
