Question 26 (1 point)

Your company packages sugar in "1 kg bags." 1 kilogram (kg) is 1000 grams (g). The automated packaging machinery inevitably varies a bit from bag to bag. Careful study shows that the actual contents the machine puts into each bag varies according to the Normal distribution with mean 1010g and standard deviation 20 g. If bags are too full, they will not contain the sugar properly, may spill in transit, and might overload a truck if too many bags are over full. If bags are not full enough, government regulatory agencies and consumers may all complain.

The top 4% of bags will almost certainly burst in transit between your packaging plant and the distributors. How heavy are the bags that will burst in transit?

Question 26 options:

a)

over 1 kg

b)	above average bags

c)

96%

d)	1045 g and heavier

e)

1.75
