A worldwide organization of academics claims that the mean 1Q score of its members is 112, with a standard deviation of 17, A randomly setected group af 40 members of this organization is tested, and the results reveal that the mean 10 score in this sample is 115,2. If the organization's daim is correct, what is the probability of having a sample mean of 115.2 or less for a random sample of this size? Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
