(0.5 pts) Set the random seed to 10. Create another random sample X2_men of 100 height values using the same mean and standard deviation. Evaluate the difference of the means of these two samples (i.e. mean of X1_men - mean of X2_men). In real life, what do we expect this difference of means to be? 0?
