Let X₁, X₂, ..., X₉be a sample of Normal random variables with expectation =72 and variance ²=49. (Namely, standard deviation of =7.) Consider the statistic T = (X-72)/[S/ 9], whereXis the sample average and S²is the sample variance. The probability P(T 2) is best described by:

Select one:

a.0.95

b.0.96

c.0.97

d.0.98
