Problem Statement

Box plot is plotted based on? Four Number Summary Three Number Summary Five Number Summary Six Number Summary Which of the following is NOT an AXIOM of probability? P(Event) >= 0 P(Sample Space) = 1 P(A union B) = P(A) + P(B) if A and B are mutually exclusive P(A and B) = P(A)*P(B) X is the sum of the squares of k independent standard normal random variables. What's the distribution of X? Normal Binomial Chi Squared Poisson What does Z score signify? How many variance away from the mean a data point is How many standard deviations away from the mean a data point is How many means away from the standard deviation a data point is Both 2 and 3 Eigenvectors of a matrix are ALWAYS orthogonal. TRUE FALSE Only for identity matrices Only for zero matrices What is the average complexity of Python's list.append() method where n is the length of the list? O(1) O(n) O(n^2) O(log n) Which graph is most likely to be used to identify potential patterns in an unprocessed data in a quick and easy ma
