The ability of lizards to recognize their predators via tongue flicks can often mean life or death for lizards. Seventeen juvenile common lizards were exposed to the chemical cues of the viper snake. Their responses, in number of tongue flicks per 20 minutes, are presented below. 557, 200, 353, 472, 438, 693, 268, 336, 744, 795, 540, 727, 676, 336, 217, 370, 523 a) Preliminary data analyses indicate that you can reasonably apply the z-interval procedure. 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: The sum of the data is 8245. Give your answers to at least 2 decimal places. Confidence interval: ( b) Which of the following is the correct interpretation for your answer in part (a)? OA. We.can be 90% confident that the mean number of tongue flicks per 20 minutes for this sample of 17 lizards lies in the interval OB. There is a 90% chance that the mean number of tongue flicks per 20 minutes for all juvenile common lizards lies in the interval C. We can be 90% confident that the mean number of tongue flicks per 20 minutes for all juvenile common lizards lies in the interval D. None of the above
