Question

Tourists watched caribou groups to determine what activities the caribou groups do at certain times of the day. A two-way table summarizing the data is provided in the table below. Does the data provide enough evidence to show that there is an association between activity and time of day? Test at the 8% level and round expected values to one decimal place.

Activity	Morning (Observed)	Morning (Expected Value)	Afternoon(Observed)	Afternoon (Expected Value)	Row Total
Travel	52		46		98
Feed	52		12		64
Social	74		34		108
Column Total	178		92		270

Expert Solution

Step 1

Null Hypothesis:

H0: There is no association between activity and time of day.

Alternative Hypothesis:

H1: There is an association between activity and time of day.

Given information:

Activity	Morning (Observed)	Afternoon(Observed)	Row Total
Travel	52	46	98
Feed	52	12	64
Social	74	34	108
Column Total	178	92	270

Expected frequency:

Formula: $E = \frac{R o w t o t a l * C o l u m n T o t a l}{T o t a l}$

Consider,

Activity	Morning (Observed)	Morning (Expected Value)	Afternoon(Observed)	Afternoon (Expected Value)	Row Total
Travel	52	64.6	46	33.4	98
Feed	52	42.2	12	21.8	64
Social	74	71.2	34	36.8	108
Column Total	178		92		270
