Question: Quantifying responses of juveniles of common lizard to natural predator cues to determine whether behavior is learned or congenital. Seventeen juvenile common lizards were exposed to chemical cues of viper snake. Their responses, in number of tongue flicks per 20 minutes, are presented in following table:

425 510 629 236 654 200

276 501 811 332 424 674

676 694 710 662 633

A. Find a 90% confidence interval for the mean number of tongue flicks per 20 minutes for all juvenile common lizards. Assume a population standard deviation of 190.0 (Note: sum of data is 9047)

B. Interpret answer from A.

C. Find 99% confidence interval for \(\mu \).

D. Why is confidence interval you found in C longer then A?

E. Draw a graph (ex: 33.6___________________39.2) (90% confidence interval) to display both confidence levels.

F. Which confidence interval yields a more precise estimate of \(\mu \). Explain.
