Chapter 10.5, Problem 10.42E
No Left Turn An experiment was conducted to compare the mean reaction times to twotypes of traffic signs: prohibitive (No Left Turn) and permissive (Left Turn Only). Ten drivers were included inthe experiment. Each driver was presented with 40 traffic signs. 20 prohibitive and 20 permissive, in randomorder. The mean time to reaction (in milliseconds) wasrecorded for each driver and ¡s shown here.
MS Excel printout for Exercise 10.42
- Explain why this is a paired-difference experimentand give reasons why the pairing should be usefulin increasing information on the difference betweenthe mean reaction times to prohibitive and permissive traffic signs.
- Use the Excel printout to determine whether there isa significant difference in mean reaction times toprohibitive and permissive traffic signs. Use thep-value approach.

Pam, Rob and Sam get a cake that is one-third chocolate, one-third vanilla, and one-third strawberry as shown below. They wish to fairly divide the cake using the lone chooser method. Pam likes strawberry twice as much as chocolate or vanilla. Rob only likes chocolate. Sam, the chooser, likes vanilla and strawberry twice as much as chocolate. In the first division, Pam cuts the strawberry piece off and lets Rob choose his favorite piece. Based on that, Rob chooses the chocolate and vanilla parts. Note: All cuts made to the cake shown below are vertical.Which is a second division that Rob would make of his share of the cake?
Three players (one divider and two choosers) are going to divide a cake fairly using the lone divider method. The divider cuts the cake into three slices (s1, s2, and s3).
If the choosers' declarations are Chooser 1: {s1 , s2} and Chooser 2: {s2 , s3}.
Using the lone-divider method, how many different fair divisions of this cake are possible?
