Question 7 3 pts We have a random variable X1 defined on Population 1. X1 has a mean value of 52 with a population standard deviation of 3. The random variable X2 is defined on Population 2 and X2 has a mean value of 50 with a population standard deviation of 4. We obtain a random sample of 625 elements from Population 1, and independently we obtain a random sample of 625 elements from Population 2. Find the probability that the difference in the sample averages X, - X, is at least 2.4. O 0.0668 O 0.0062 O 0.0376 O 0.9772 O 0.0228
