The dataset “scatter_data. csv” contains measured properties of sonar waves scattered off objects. The objects of interest could be metallic (M) or rocky, (R) as given in the last column. In the data
given, there are 60 observed signal characteristics, and the last column is M or R for Metal or Rock.
The task here is to develop a model that can predict the type of object being scanned based on reflected
sonar wave properties.
Use a Naive Bayes classifier to develop a model for this classification problem. Use a random seed of
42 and shuffle the data first. Take the first 40 rows of the shuffled set as test data and the rest as training
data. Train the model with the training data and evaluate the model’s accuracy based on the test dataset.
Submit a runnable jupyter notebook. Follow the template I gave you, retaining the comments in
the markups.

Which of the following methods could be considered a “best practice” in terms of informing respondents how their answers to an on-line survey about personal information will be protected? respondents are informed that investigators will try to keep their participation confidential; however, confidentiality cannot be assured. respondents are informed that a research assistant will transfer all the research data to a password-protected computer that is not connected to the internet, via a usb flashdrive. the computer is located in a research team member’s office. the investigator uses the informed consent process to explain her institution’s method for guaranteeing absolute confidentiality of research data. the investigator uses the informed consent process to explain how respondent data will be transmitted from the website to his encrypted database without ever recording respondents’ ip addresses, but explains that on the internet confidentiality cannot be absolutely guaranteed.

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
