python code Problem 7 Define a function named z and have it take 3 arguments: score , mu (sample mean) , sigma (standard deviation).. Return the calculated z-score. Use your z function on this data to show it works: You have a test score of 190. The test has a mean (μ) of 150 and a standard deviation (σ) of 25. Now define a function named std_error and have it take 2 arguments: sigma (standard deviation) , and n. Return the calculated standard error Use your std_error function (you can assume a sample size of 10) Print the answer rounded to the 2nd decimal place.
