Apply what you have learned
Suppose your class had been twice as large, but you had obtained the same sample proportion choosing scissors, how would that affect the p-value?
(o) Using this hypothetical scenario, what are the new values for n and ?
(p) What do you think will be true about the p-value for this analysis? (choose one)
larger | smaller | stay the same |
---|
(q) Use either the Reese's Pieces applet or the Normal Probability Calculator applet to obtain the p-value for these hypothetical data. Include a screen capture of your output displaying the p-value.
(r) Did the p-value change? In the direction you conjectured? Do these data provide stronger, weaker, or similar evidence that students at your school pick scissors less than one-third of the time?
