Assume that water bottle content is normally distributed with mean 120 and standard deviation 15. If one item is randomly selected, what is the probability that it is: 27) Above 125 (a) 0.333 (b) 0.369 (c) 0.748 (d) 0.631 (e) 0.252 28) Below 110 (a) 0.378 (b) 0.117 (c) 0.631 (d) 0.369 (e) 0.252 29) Between 110 and 125 (a) 0.117 (b) 0.378 (c) 0.748 (d) 0.369 (e) 0.252 30) Which values separate 7% lowest and 7% highest from the rest of the values?
