The boxplot shows that the median is closer to the lower quartile, indicating that the majority of the batteries lasted for a shorter time. The upper whisker is longer than the lower whisker, and there are a few outliers on the right side, suggesting that there were some batteries that lasted for a significantly longer time. This skewedness to the right indicates a long tail on the right side, and therefore, the distribution is right-skewed.
