Research question: Is the mean commute time greater than 15 minutes?

H 0: μ = 15

H a: μ > 15

Data were collected from a sample of 50 adults. The sample mean was 18.240 minutes with a standard deviation of 13.074 minutes. The sample data were slightly skewed to the right. The shape of the population distribution is unknown.

In this scenario, is it appropriate to use the t distribution to approximate the sampling distribution?
