The marketing manager of a pharmaceutical company believes that more females than males use its acne medicine. In a recent survey, 2500 teenagers were asked whether or not they use that particular product. The responses, categorised by gender, are summarised below. $$\begin{array} { | l | l | l | }
\hline & \text { Use acne medicine } & \begin{array} { l }
\text { Do not use acne } \
\text { medicine }
\end{array} \
\hline \text { Female } & 540 & 810 \
\hline \text { Male } & 391 & 759 \
\hline
\end{array}$$ Do these data provide enough evidence at the 10% significance level to support the manager's claim?
