Write a class named SatData that reads a JSON file containing data on 2010 SAT results for New York City and writes the data to a text file in CSV (comma-separated values) format. It just needs to read a local JSON file - it doesn't need to access the internet. Specifically, your class should have an init method that reads the file, and it should have a method named save_as_csv that takes as a parameter a list of DBNs (district...
Q3 [Number Searching] (25%) Given two non-negative integers A (data type: int) and B (data type: int), write a C++ program to determine whether A contains B, wherein "contains” means an exact match. For example, • If A is 12345 and B is 234, A contains B, where the matching part is underlined in A. • If A is 12345 and B is 235, A does not contain B, even A has the digits 2, 3 and 5. It is...
Haskell coding problem please do the last 3
Problem One (Non-Polymorphic Type Inference): Give the type of the following expressions. We assume that we can have Integer and Bools as defined in the Haskell Prelude. Assume that all arithmetic operators in these examples operate only on Integers, so the type of (+) is Integer->Integer -» Integer. data D a = A Integer | B Bool | C a data Pair a b = Pab data List aNil | Cons a...
Suppose we wished to compare 5 group means. We could perform an ANOVA, or we could perform several two-sample t tests. If we were to do the latter, how many different t tests would we have to perform?
Visualizing Data Exercise For each dataset, circle the type of figure that would be most appropriate. Sketch the figure the actual values do not matter - we are interested in what is labeled, how it is labeled, and the basic gist of what the figure might look like) and include a figure legend. 1. We measured the fat content of three brands of donut and wish to show how the mean and standard deviation of the fat content compares among...
