   Question

   

   Above is the correlation matrix showing the correlation between the degree of enjoyment experienced in literature classes earlier in school and subsequent attitudes toward reading. Via bootstrapping, the 95% confidence interval is shown running from .230 to .385.

   What does this interval mean?

   
   
   1. TRUE: If we assume that this sample is among the 95% of samples that contain the population value, the correlation in the population is between .230 and .385.
   2. FALSE: For 95%, you can be confident that the population value is between .230 and .385.
   3. FALSE: There is a 95% chance that the population value in the interval is between .230 and .385.
   4. FALSE: With 95% confidence, the population value fluctuates between .230 and .385.
   
   
   1. True
   2. False
   3. False
   4. False
