Julio is buying a carton of blueberries that has a mass of 100 grams. is it reasonable to say that there are 250 blueberries in the carton? explain.

It is not reasonable to say that there are 250 blueberries in the carton because the average weight of the blueberry in the carton does not make sense. The average weight of the blueberry in the carton is 0.4 gram (=100/250) and the normal average weight of blueberry is 0.66 to 1.5 gram. This gross calculation has not yet included the carton's mass.

13.92

Step-by-step explanation:

We have that the critical z-score associated with 85% to the left is 1.04, we know that by table.

So we have to:

m + z * (sd) = 16

where m is the mean, z is the critical z-scor and sd is the standard deviation, if we replace we are left with:

m + 1.04 * (2) = 16

m = 16 - 1.04 * (2)

m = 13.92

Therefore, the average weight if 85% of cucumbers weigh less than 16 ounces is 13.92
