Question

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.

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
