Question

Burger King is suspected of under-filling its French fry containers. Burger King advertises a true mean count of 50 chips per sleeve, and the company website reports a standard deviation of 5 chips. A Consumer Reports office is skeptical of this fifty-fry claim and randomly purchases 100 sleeves (being sure to get them from different locations, on different dates, etc.), producing a sample mean count of 49.1 fries.

A.) Label all four of the numbers in the preceding paragraph with their correct symbols.

B.) Jessica stops by the Consumer Reports offices, sees the sample results, and says, “A-ha! Of course Burger King is lying about their “50 fries” claim – 49.1 is less than 50!” In a couple of complete sentences or less, explain why her conclusion isn’t warranted just yet.
