a/ You are a city inspector. You go undercover to a bakery and buy 30 loaves of bread marked 500 g. Back at the lab you weigh them and find their masses to be 493, 503, 486, 489, 501, 498, 507, 504, 493, 487, 495, 498, 494, 490, 494, 490, 497, 503, 498, 495, 503, 496, 492, 492, 495, 498, 490, 490, 497, and 482 g. You go back to the bakery and issue a warning. Why ?

b/ Later you return to the bakery (this time, they know you). They sell you 30 more loaves of bread. You take them home, weigh them, and find their masses to be 504, 503,503, 503, 501, 500, 500, 501, 505, 501, 501, 500, 508, 503, 503, 500, 503, 501, 500, 502, 502, 501, 503, 501, 501, 502, 503, 501, 502, 500 g. You are satisfied, because all the loaves weigh at least 500 g. But your boss reads your report and tells you to go back and close the shop down. What did she notice that you missed ?

Solution

a) A warning is issued because the breads weighed less than that marked on the bread.

b)The boss asks to close the shop down because since the shopkeeper knows the inspector so he has given bread loaves weighing greater than or equal to 500g but he is misleading the other customers.
