The Frequentist approach looks at Question 17 options: the long-term relative frequency of events occurring both single events occurring and the long-term relative frequency of events occurring a single event occurring neither single events occurring nor the long-term relative frequency of events occurring For data that is approximately normally distributed, any observation more than 1 standard deviation away from the mean is an outlier. Question 26 options: True False
You are working as a data scientists and you have received data on house prices in the Boston region. The data set contains the following variables: • crim: per capita crime rate by town • zn: proportion of residential land zoned for lots over 25,000 sq.ft. • indus: proportion of non-retail business acres per town • chas: Charles River dummy variable (= 1 if tract bounds river; 0 otherwise) • nox: nitric oxides concentration • rm: average number of rooms per dwelling •age: proportion of owner-occupied units built prior to 1940 • dis: weighted distances to five Boston employment centers • rad: index of accessibility to radial highways • tax: full-value property-tax rate per $10,000 ptratio: pupil-teacher ratio by town • b: 1000(Bk - 0.63)² where Bk is the proportion of blacks by town Istat: % lower status of the population • medv: Median value of owner-occupied homes in $1000s Given this information: 1. Download the dataset boston.csv and open it as a PANDAS dataframe. 2. Using 'medv'…
You are building a classification model to predict whether a firm will go bankrupt within the next 5 years. When you collect the data, you find that the number of instances of firms that went bankrupt is smaller than the number of cases of firms that did not go bankrupt. Specifically, only 7% of the firms went bankrupt, while the rest did not go bankrupt. Once you build the classification model, you need to compare performance against a baseline. Which of the following would be an appropriate baseline? O Always predicting that the firm does not go bankrupt O Making a prediction that a firm goes bankrupt with 7% probability O Always predicting that the firm goes bankrupt Making a prediction from the set (bankrupt, not bankrupt) with equal probability

The mayor of a city is interested in learning what goals are most important for residents of the city. 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. c Visiting multiple new neighborhoods to collect more survey responses. d Having her staff collect the data using an app rather than paper surveys.
