Answer:
By observing above box plot, it is clear that inter quartile range of second sample box plot is large as compare first sample box plot.
Hence, the dispersion of the second sample is the largest.

15. Multiple Choice Question Consider two independent normal populations. A random sample of size n = 16 is selected from the first normal population with mean 75 and variance 288. A second random sample of size m - 9 is selected from the second normal population with mean 80 and variance 162. Assume that the random samples are independent. Let X, and X, be the respective sample means. Find the probability that X1 + X, is larger than 156.5. A....
