It is believed that seat position within a bus may have some effect on whether one experiences motion sickness. The table below classifies each person in a random sample of bus riders by the location of his or her seat and whether nausea was reported.

Contingency table results:
Rows: seat
Columns: None


Chi-Square test:

Select the appropriate interpretation of the results.

Using a 0.05 level of signficance, there is not sufficient evidence to conclude that seat position and level of nausea are associated.

Using a 0.05 level of signficance, there is sufficient evidence to conclude that seat position and level of nausea are associated.

All bus riders who seat in the rear are about 3 times as likely to experience nausea than those who sit in the front.

Using a 0.05 level of signficance, there is sufficient evidence to conclude that seat position and level of nausea are independent.

nausea no nausea Total
front 58 870 928
middle 166 1163 1329
rear 193 806 999
Total 417 2839 3256

Solution

Using a 0.05 level of signficance, there is not sufficient evidence to conclude that seat position and level of nausea are associated.

p-value is less than 0.0001 and that means that is less than 0.05

so we conclude that there is not sufficient evidence to conclude that are associated
