Final answer:
A) Digit reader: categorical. B) Movie recommendations: categorical. C) Spam filter: categorical. D) Hospitalizations: continuous.
Step-by-step explanation:
A) The outcome of the digit reader is categorical. The digit reader can only output discrete values representing the digits from 0 to 9. For example, if the digit reader scans a handwritten number and recognizes it as a '7', the output is a categorical value of '7'.
B) The outcome of movie recommendations is also categorical. The recommendations are based on algorithms that consider various factors such as genre, rating, and viewing history. The recommendations are categorical suggestions of movies to watch.
C) The outcome of the spam filter is also categorical. The filter categorizes incoming emails as either spam or not spam based on certain criteria such as keywords, sender reputation, and email structure.
D) The outcome of hospitalizations is continuous. It represents the number of patients admitted to a hospital, which can take on a range of numeric values.
