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 8279.

The CI of the 'true mean= [455, 609]

Step-by-step explanation:

Please see attachment.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
