Answer:
A confidence interval for a mean should be constructed to estimate the variable of interest.
Step-by-step explanation:

Since it is a confidence interval, instead of a single number for the mean, the result shows a lower estimate and an upper estimate of the mean. In this experiment, the confidence interval cannot be for a proportion since the population of healthy males is unknown, but the calculation is being done with a sample of 75 healthy males.
