Summary statistics computed for two population (A & B) are as follows: meanA=100, sigmaA=45, meanB-30, sigma B=14. If two samples of equal sizes 15 are independently drawn from these two population. Find the probability that sample A will have mean of 90.7 more than sample B.
A. 0.152
B. 0.529
C. 0.251
D. 0.0445
