Question 1180687: Snakes deposit chemical trails as they travel through their habitats. These trails are often detected and recognized by lizards, which are potential prey. The ability to recognize their predators via tongue flicks can often mean life or death for lizards. Scientist from Kenyatta University were interested in quantifying the responses of Juveniles of the common lizard to the natural predator cues to determine whether the behavior is learned or congenital. 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 in the following table:
425 510 629 236 654 200 710 276 633
501 811 332 424 674 676 662 694
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 190.
B)Interpret your answer from part A.

n = 17
x̄ = 532.1765 0r 533 rounding up to whole number
sigma = 190 population
z (90% confidence interval, df = 16) is 1.75
ME = = 80.6431
533 - 81 < < 533 + 81
CI: ( 452, 614)
