- Find the z-score that cuts off 65% in the body on the left.Find the z-score that cuts off 70% in the body on the right.The area between a negative Z score and a positive Z score can be found by adding the Z scores and finding the area in the Z score table for the summed Z scores adding the areas between each Z score and the mean subtracting the Z scores from each other subtracting each Z score from the mean and adding the results
- The molecular weight of a particular polymer should fall between 750 and 1,035. Thirty samples of this material were analyzed with the results X-bar = 902 and s = 90. Assume that molecular weight is normally distributed.The diameter of a metal shaft used in a disk-drive unit is normally distributed with mean 0.2508 in. and std. dev. 0.0005 in. The specification on the shaft have been established as (0.25-0.0015 in, 0.25+0.0015in) If the process mean has been adjusted to 0.25 in, what fraction of the shafts produced does NOT conform to specifications? a). 0.0027 b). 0.0013 c).0.08 d). 0.16Assume that the weight of hamsters is Normally distributed with μ = 1.2 lbs and σ = 0.25 lbs. Suppose I randomly select 5 hamsters. What is P(X < 1.15)? (Use 3 decimal places)
