The real answer
Nov 12-8:34 AM
Mammograms Many women choose to have annual mammograms to screen for breast cancer after age 40. A mammogram isn’t foolproof. Sometimes the test suggests that a woman has breast cancer when she really doesn’t (a “false positive”). Other times the test says that a woman doesn’t have breast cancer when she actually does (a “false negative”). Suppose the false negative rate for a mammogram is 0.10.
(a) Interpret this probability as a long-run relative frequency.
(b) Which is a more serious error in this case: a false positive or a false negative? Justify your answer.

A family restaurant chain wants to test the market for a new
menu item: a grilled chicken sandwich with chipotle salsa.
They are interested in both how to market the item and the
right price to charge for it. They decide to offer the sandwich at
60 different restaurants in the chain, using two different
descriptions on the menu. Half the restaurants’ menus will
emphasize “healthy eating” and half will emphasize “value.”
They further plan on offering the new sandwich for a charge of
either a High, Medium, or Low price. Each restaurant will have
identical menus with identical locations in the menu for the
sandwich. The only differences in the menus will be those
previously mentioned. After a month, they will measure what
proportion of customers order the new sandwich based on the
menu options.
