A classic data set for investigating categorical variables deals with the RMS Titanic. The Titanic sank in the North Atlantic Oc

ean on April 15, 1912. There were more than 2,000 passengers and crew on board and more than 1,500 did not survive. The data set titanic.jmp located with this homework contains data on 887 passengers. For each passenger, the variables Class (class of the passenger) and Survived (whether or not the passenger lived) were recorded. A main question of interest is whether there is an association between class and survival.
1. Identify the Who for this data set.
2. Identify the What for this data set.
3. Use JMP to obtain the distribution of the variable Survived. Print out the output and turn it in with this assignment. See the Chapter 2 JMP guide for help.
4. What proportion of these passengers did not survive?
5. One variable that could be associated with the survival of a passenger is their Class. In studying this relationship, which variable is the explanatory variable? Circle the appropriate answer. Class Survived
6. Use JMP to obtain a contingency table and mosaic plot of the relationship between the Class of a passenger and whether or not they Survived. Change the contingency table so that it includes only the Count and Row % values. Print out the output and turn it in with this assignment. See the Chapter 2 JMP guide for help.
7. Explain the meaning of the number 119 from the contingency table.
8. Give the conditional distribution of Survived given that the passenger was in First class.
9. Compare this conditional distribution to the overall marginal distribution of Survived. Are the two distributions similar to each other, or are they different? Explain.
10. Based on the contingency table and mosaic plot, does it appear there is an association between Class and Survival? Circle the appropriate answer below. Then given an explanation for your answer. Yes, there is an association No, there is not an association Explain your answer:

What is the slope of (15,9), (-14,-9)
Lady bird [3.3K]
The formula for slope:

m = \frac{y_{2} - y_1 }{x_2-x_1}

\frac{-9-9}{-14-15}

-9-9 = -18
-14-15 = -29

\frac{-18}{-29}
