Considering the hypothesis tested and the rejection of the null hypothesis, it is found that the final conclusion is that the standard deviation of calories consumed by adult males at a sports arena is less than 155 calories.

What are the hypothesis tested?

At the null hypothesis, it is tested if the standard deviation is of 155 calories, that is:

$H_0: \sigma = 155$.

At the alternative hypothesis, it is tested if it is less than 155 calories, that is:

$H_1: \sigma < 155$.

What is the final conclusion?

The null hypothesis is rejected, hence the final conclusion is that the standard deviation of calories consumed by adult males at a sports arena is less than 155 calories.
