19. A random sample of 7 = 51 middle school kids is taken from a population whose IQ is approximately normally distributed with mean u = 110 and standard deviation o = 10. Let's* be the sample variance (i.c., s is the sample standard deviation). Then P(s > 11.2401) is approximately (a) 0.025; (b) 0.050; (c) 0.100; (d) 0.900; (e) None of the above
