- As the evidence on the adverse effects of cigarette smoke grew, people tried many different ways to quit smoking. Some people tried chewing tobacco or, as it was called, smokeless tobacco. A small amount of tobacco was placed between the cheek and gum. Certain chemicals from the tobacco were absorbed into the bloodstream and gave the sensation of smoking cigarettes. This prompted studies on the adverse effects of smokeless tobacco. One study in particular used 40 university students as subjects. Twenty were given smokeless tobacco to chew, and twenty given a substance that looked and tasted like smokeless tobacco, but did not contain any of the harmful substances. The students were randomly assigned to one of the groups. The students' blood and heart rate were measured before they started chewing and 20 minutes after they had been chewing. A significant increase in heart rate occurred in the group that chewed the smokeless tobacco. Answer the following questions. a. What type of study…Computer Science Scenario: Suppose you were to let your friend use your computer for a couple of hours in order for them to complete their homework assignments.

- (a) A school is conducting a survey of students to learn more about how they get to school. Students were asked how they travel to school, how long it takes them to get to school, what time they arrive at school, and for a description of their most significant challenges when traveling to school. Several rows of the data collected are shown in the table below. Student ID How Travel How Long Time Arrive Biggest Challenges 738192 Car 10 minutes 7:30 am None 781401 Car 20 minutes 7:45 am 72001 Car 5 hours 7:40 am 74012 Bus 10-20 minutes 7:35 am Sister sometimes sleeps in and I miss my bus Walk 1 hour 75441 7:30 am 73109 Walk 20 mins 7:45 am 76120 Bus twenty minutes 7:35 am 73012 Car 15 min 7:20 am Waking up!

Members of her staff visit one of the many neighborhoods in the city and ask 20 residents to fill out a survey. The mayor is concerned that the survey may be biased and not accurately reflect the overall interests in her town. Which of the following strategies is MOST likely to address concerns about the data being biased or inaccurate. A Finding the same people surveyed previously to ask more detailed questions. B) Visiting the same neighborhood to collect more survey responses Visiting multiple new neighborhoods to collect more survey responses D Having her staff collect the data using an app rather than paper surveysYou've been provided four different machine learning algorithms to use in conjunction with a dataset for supervised learning.
