Question

question 1 of 10
a medical company tested a new drug for possible side effects. the table shows the relative frequency that a study participant
experienced the side effect.

	side effect	no side effect
teens	0.19	0.31

do these data suggest an association between age and experiencing side effects?
a. no. a greater percentage of both adults and teens had no side effects.

b. yes. a greater percentage of teens experienced side effects than adults.

c. no. adults were as likely to experience side effects as teens.

d. yes. a greater percentage of adults experienced side effects than teens.

Explanation:

Step1: Calculate adult side effect %

Adult side effect relative frequency: \(0.05\), so percentage is \(0.05\times100 = 5\%\).

Step2: Calculate teen side effect %

Teen side effect relative frequency: \(0.19\), so percentage is \(0.19\times100 = 19\%\).

Step3: Compare percentages

\(19\% > 5\%\), so teens have a greater percentage of side effects.

Answer:

B. Yes. A greater percentage of teens experienced side effects than adults.
