Answer: Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
Step-by-step explanation:
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.
Answer:
2.7%
Step-by-step explanation:
Actual width = 45.5 meters.
Incorrect width = 44.25 meters.
Error = 45.5 - 44.25 = 1.25
Percentage error =
= 2.74
≈ 2.7%
Hence, the percentage error = 2.7% which is given in the third option.
