In this problem, you are provided with a dataset that pertains to products sold by an online retailer. You are required to answer the following questions to demonstrate your understanding/calculation of linear regression and logistic regression. Specifically, if any decimal values appear at any step of the calculation (not just in the final result), you must round them to integers for consistency.   1. (5 points) Which feature(s) and output from the above dataset would you choose for Logistic Regression, and why?   2. (15 points) If we define Price and Weight as the output and feature, respectively, please use the closed-form solution to find the optimal line for the linear regression above.

In the dataset below, we have two features: Science and Humanities scores. Please perform normalization on these two features as required. Specifically, if any decimal values appear at any step of the calculation (not just in the final result), you must round them to two decimal places for consistency. 1. (10 points) Please normalize the Sciences feature using the Min-Max Scaling method.   2. (10 points) Please normalize the Humanities feature using Standardization.

Which of the following are accurate regarding the epithelial tissue in the body? They are radiosensitive cells that line and cover body tissue. They are found in the mucousal lining of the respiratory tract. The regenerate through a process called mitosis.

In reference to point mutations: Dominent mutations are usually expressed in the offspring Recessive mutations may be not be expressed for several generations Radiation is thought to primarily cause recessive mutations
