Houseflies have pretty short lifespans. Males of a certain species have lifespans that are strongly skewed to the right with a mean of 26 days and a standard deviation of 12 days. A biologist collects a random sample of 10 of these male houseflies and observes them to calculate the sample mean lifespan. We can assume that the houseflies in each sample are independent.

What is the probability that the mean lifespan from the sample of 10 houseflies xˉ is less than 24 days?
