Since we have given that
Number of coffee drinkers = 10000
Number of whom developed anxiety = 500
Number of non coffee drinkers = 20000
Number of whom developed anxiety = 200
So, probability of getting anxiety from coffee drinkers =
Probability of getting anxiety from non coffee drinkers =
so, Relative risk of anxiety associated with coffee use is given by
Hence, Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
