13. Before applying to law school, students must take the LSAT. Before applying to medical school, students must take the MCAT. The LSAT has an average score of 151 with variance 100, while the MCAT has an average score of 25.1 with variance 49. Suppose a student takes both tests and scores 172 on the LSAT and 37 on the MCAT. Which exam did the student do relatively better on?

Question

Can someone please help with this question. Will give thumbs up 

(a) Assuming we have typed this into list properly into Python as 1ist, what code would you type to determine the sample mean and sample variance? Assume as before that we have loaded numpy as usual. (b) What would the output of Python be (assuming you've coded things cor- rectly)? Meaning, what is the sample mean and variance of this data set? 13.

Suppose you run a clinical trial for a new prescription drug on 25 patients, and determine that the sample mean of resting heart rate is +2 beats per minute, with a variance of 5 beats per minute squared. Your drug, however, was expected to have little to no effect on resting heart rate. You are now intrigued to find out if this happened by random chance, or if there is some major problem with your test. (a) Which of the following would be the benchmark value, T, to compare future clinical trials against? 5. enough info
