# peer response 39

For your response to a classmate (two responses required, one in each option), solve your classmateâ€™s confidence interval or hypothesis test problem, using a significance level not previously used Make sure that you use appropriate terminology and specify whether you are using the classical method or the p-value method.

Response 1:

I was interested in knowing if the average weight of an acorn from a white oak tree was different than the average weight of an acorn from a chestnut oak tree. I collected 8 random samples from a white oak tree and came out with the weights of: 1.2 g, .9 g, 2.0 g, 1.4 g, 1.3 g, .7 g , 1.1 g, 1.0 g. I collected 8 random samples from a chestnut oak and came out to the weights of: .9 g, 1.2 g, 2.2 g, 1.1 g, 2.4 g, 1.0 g, 2.0 g, .9 g.

 White Oak Chestnut Oak 1.2g .9g .9g 1.2g 2.0g 2.2g 1.4g 1.1g 1.3g 2.4g .7g 1.0g 1.1g 2.0g 1.0g .9g

Compute a 95% confidence interval of the given population means.

Response 2:

The makers of the anxiety drug Xanax, reported that 26 of the 374 subjects who took the drug experienced hallucinations as a side effect, compared to 8 of the 210 subjects who were on a placebo. None of patients knew which treatment they were given. In the sample, a larger percentage of the people on the drug experienced hallucinations, but is this percentage enough to say that the entire population on the drug would experience more hallucinations? Use the Î± = 0.05 level of significance.
