The correlation coefficient of 0.49 indicates a moderate positive correlation between gender and student aptitude scores. In hypothesis testing, we generally reject the null hypothesis if the correlation coefficient is significantly different from zero. Therefore, we reject the null hypothesis and conclude that there is a statistically significant correlation between gender and student aptitude scores.
