Since the sample mean is 3 and the margin of error is 0.5, we can calculate the lower and upper limits of the confidence interval as follows:

Lower limit = mean - margin of error = 3 - 0.5 = 2.5
Upper limit = mean + margin of error = 3 + 0.5 = 3.5

Therefore, the 95% confidence interval for the mean number of hookups is 2.5 to 3.5.
