Question

When the Titanic sank, passenger survival rates were recorded along with additional information like their name, what class ticket they had, their age, and whether or not they had children. Some of these factors may predict whether or not a passenger was likely to survive the accident. The data set "Titanic survival.jasp" contains actual recorded data from the event. Using the variables "Class" and "Survived", conduct a Chi-Square Test for Independence, at alpha = 0.05, to see if a passengers ticket class (first, second, or third class) is significantly associated with their survival rates.

Identify the correct alternative hypothesis

 
  • A.

    HA: Titanic passenger class and survival rates are not independent

  • B.

    H0: Titanic passenger class and survival rates are independent

  • C.

    HA: At least one Titanic passenger class is related to survival rates

  • D.

    H0: At least one Titanic passenger class is not related to survival rates
