Check Your Understanding
Mythbusters investigated the question "Is yawning contagious?" Here's a brief recap. Each subject was placed in a booth for an extended period of time and monitored by hidden camera. 34 subjects were given a "yawn seed" by one of the experimenters: that is, the experimenter yawned in the subject's presence before leaving the room. The remaining 16 subjects were given no yawn seed.

Multiple Choice
STATE
Which is the appropriate set of hypotheses?
Ho: p1-p2 = 0 yawning is not contagious
Ha: p1-p2 > 0 yawning is contagious
Ho: p1-p2 > 0 yawning is contagious
Ha: p1-p2 = 0 yawning is not contagious
Ho: p1-p2 = 0 yawning is not contagious
Ha: p1-p2 < 0 yawning is contagious

Fill in the Blanks
STATE the significance level (as a decimal to 2 places)
Type answer...
6
Multiple Choice
PLAN
Name the procedure.
1 sample z test for proportions
2 sample z test
2 sample z test for p1-p2
2 sample z interval for p1-p2
7
PLAN - Random and 10% Conditions
Random - used random assignment. Now we can show causation
10% condition - no sampling here so we don't need to check this (experiment)
8
Multiple Choice
PLAN
Has the Large Counts/Normal condition been met for both samples?
Yes, it has been met for both samples.
No, it has not been met for either sample.
It was only met for sample with the yawn seed (p1) and not for the second sample (p2)
It was only met for the sample without the yawn seed (p2) and not for the first sample (p1)
