The claim is that the white blood cell counts of adult females are normally? distributed, with a standard deviation equal to 2.352.35. A random sample of 3737 adult females has white blood cell counts with a mean of 7.497.49 and a standard deviation of 2.422.42. The test statistic is nothingm. ?(Round to three decimal places as? needed
The test statistic () = (n - 1)s2/
= (37 - 1) * (2.42)^2/(2.35)^2
= 36 * (2.42)^2/(2.35)^2
= 38.177
