Widowed 55
Divorced 222
  1. What is the correct statistical test to use? Select an answer Independence Goodness-of-Fit Homogeneity Paired t-test
  2. What are the null and alternative hypotheses? H0:H0: H1:H1:
  3. The degrees of freedom =
  4. The test-statistic for this data = (Please show your answer to three decimal places.)
  5. The p-value for this sample = (Please show your answer to four decimal places.)
  6. The p-value is Select an answer greater than less than (or equal to)
  7. Based on this, we should Select an answer fail to reject the null accept the null reject the null
