Analysis
Now you are ready to analyze the actual study. In the actual study, Dr. Güntürkün observed 80 of the 124 couples in his sample turned to the right.
- Use the One Proportion applet below to create the hypothesized null (exact binomial) distribution assuming
= 0.74 and n = 124. - Enter the observed numer of successes.
- Check the two-sided box.
(g) Include a screen capture of your output, showing the two-sided p-value, in your lab report.
(h) What values does the applet consider as or more extreme as the observed number of successes?
(i) Based on this two-sided p-value, would you say there is convincing evidence that differs from 0.74? Explain your reasoning.
