Question

On the morning of March 5, 1996, a train with 14 tankers of propane derailed near the center of the small Wisconsin town of Weyauwega. Six of the tankers were ruptured and burning when the 1700 residents were ordered to evacuate the town. Researchers study disasters like this so that effective relief efforts can be designed for future disasters. About half of the households with pets did not evacuate all of their pets. A study conducted after the derailment focused on problems associated with retrieval of the pets after the evacuation and characteristics of the pet owners. One of the scales measured "commitment to adult animals," and the people who evacuated all or some of their pets were compared with those who did not evacuate any of their pets. Higher scores indicate that the pet owner is more likely to take actions that benefit the pet. Here are the data summaries.

Analyze the data and prepare a short report describing the results. (Use = 0.01. Round your value for t to three decimal places and your P-value to four decimal places.)

Explanation / Answer

H0: There is no difference between means of two groups

H1: There is a difference between means of two groups

alpha:1%

Test statistic:

t=3.3127

Conclusion:

P value=0.0011 <0.01,

we reject the H0. Hence claim is significant
