Let S be the event that randomly selected college student has taken a statistics course
Let S be the event that randomly selected college student has taken a statistics course and let C be the event that the same student has taken calculus 1 course. Suppose P(S) = 0.4, P(C) = 0.3 and P(S and C) = 0.2.
Find the probability that a student has taken at neither statistics nor calculus.
Let S be the event that randomly selected college student has taken a statistics course and let C be the event that the same student has taken calculus 1 course. Suppose P(S) = 0.4, P(C) = 0.3 and P(S and C) = 0.2.
Find the probability that a student has taken at least one of the two courses.

Problem 1: See Dataset HIFA19Q1 .mtx In a packing plant, a machine packs cartons with jars. It is supposed that a new machine will pack faster on the average than the machine currently used. To investigate this issue, the times it takes each machine to pack forty cartons, twenty each, are recorded. Conduct different types of descriptive analysis of the data of this experiment as outlines in the questions below: 1. Use a suitable graphical method to compare the packing...
