Final answer:

The tenth time is likely an outlier due to the significant increase in standard deviation.

Step-by-step explanation:

In order to determine if the tenth time is likely an outlier, we can compare the increase in standard deviation. The original standard deviation is 1.1, and when the tenth time is added, it increases to 1.5. Since the standard deviation has increased significantly, it suggests that the tenth time is likely an outlier.
