QUESTION 2 Now consider the data in more detail, by class of traveller, separately for women and men First class 146 4 WOMEN survived died Second class 104 13 Third class 103 141 Crew 20 534 MEN survived died First class 57 118 Third class 75 387 Crew 192 670 Second class 154 Separately for women and men test the hypothesis that there were no differences in survival by class of traveller. How do you interpret your results? Fill in the blanks with "small or "large" and "a" or "no" to indicate whether a difference exists in the survival rates of the different classes For women the p-value was For men the p-value was indicating there was difference in the survival rates of the different classes , indicating there was difference in the survival rates of the different classesExplanation / Answer
For women:
H0: There are no differences in survival by class of Traveler.
Ha : Here are significant difference in survival by class of traveler.
Observed Class:
Expected Class:
Chi- square Values :
X2 = (Oi - Ei)2 / Ei
X2= 650.85
p - value = 9.5 * 10 -151
For women the p - value was small, indicating there was a difference in survival rates of the different classes.
For men:
H0: There are no differences in survival by class of Traveler.
Ha : Here are significant difference in survival by class of traveler.
Observed Value :
Expected Value :
Chi - square value
X2= 37.99
p - value = 2.84 * 10-8
For men the p - value was small, indicating there was a difference in survival rates of the different classes.
