For the “leaning” version of the study from the previous question:
a. Statistic: How many times did Krieger choose the correct object? Out of how many attempts? Thus, what proportion of the time did Krieger choose the correct object?
b. Simulate: Using an applet, simulate 1,000 repetitions of having the dog choose between the two objects if he is doing so randomly. Report the null and standard deviation.
c. Based on the study’s result, what is the p-value for this test?
d. Approximately what proportion of the 10 attempts would Krieger have needed to get correct in order to yield a p-value of approximately 0.05?
