For education purposes, consider this dataset to be a sample of size 60 taken from a much wider population for statistics students. Use R to find a 99% confidence interval for the mean of the population. Choose the most correct (closest) statement below. a. Your confidence interval is (72.38912, 76.41088) beats per minute and it is narrower than a 90% confidence interval created from this data. b. Your confidence interval is (72.88831, 75.91169) beats per minute and is narrower than a 90% confidence interval. c. Your confidence interval is (72.88831, 75.91169) beats per minute and it is wider than a 90% confidence interval created from this data. d.

Exercise 2a Generate a random 3 x 3 matrix of integers between -6 and 6 that has a dominant eigenvalue. Either re-run the code until you get a matrix with a dominant eigenvalue, or duplicate the code below several times until you see a matrix with a dominant eigenvalue. Then manually enter this as the matrix A, so when we grade your assignment, the matrix doesn't get re-randomized. % Put your code here A = randi ([-6 6],3) A = 3x3 eig (A) 455 ans = 3x1 ܩ ܚ 2 -5 10.5990 -1.8175 3.2185 -3 1 6 %Hard code the matrix you generated here % so when we grade your assignment the value of the matrix won't % re-randomize Exercise 2b Find the dominant eigenvalue of the matrix A from the previous problem.

Use the sacramento.csv file to complete the following assignment. Create a file, sacramento.py, that loads the .csv file and runs a logistic regression. The regression should predict whether or not a house has 1 or more than one bathroom based on beds, sqft, and price, in that order.You will need to create a new variable from baths, and it should make it such that those observations of 1 bath correspond to a value of 0, and those with more than 1 bath correspond to a 1. Make sure to add a constant using sm.add_constant(X) Your file should print the results in this way: print(mod.params.round(2)) print(mod.pvalues.round(2)) print('The smallest p-value is for sqft') Please use sm.add_constant(X)! In Jupyter Notebook please! Please use the sys module!
