Final answer:
The mean of the sample proportion of international students in random samples of size 50 is 3.35.
Step-by-step explanation:
The mean of the sample proportion of international students in random samples of size 50 can be found by multiplying the proportion of international students by the sample size. In this case, the proportion of international students is given as 6.7% or 0.067, and the sample size is 50. So, the mean is 0.067 * 50 = 3.35.
