OK, version v1.12.5 ===================================================================== Successfully logged in as [email protected] 1.1 1. Plot the Vote Four candidates are running for President of Dataland. A polling company surveys 1000 people selected uniformly at random from among voters in Dataland, and it asks each one who they are planning on voting for. After compiling the results, the polling company releases the following proportions from their sample: Candidate Proportion Candidate C 0.47 Candidate T 0.38 Candidate J 0.08 Candidate S 0.03 Undecided 0.04 These proportions represent a uniform random sample of the population of Dataland. We will attempt to estimate the corresponding population parameters , or the proportion of the votes that each candidate received from the entire population. We will use confidence intervals to compute a range of values that reflects the uncertainty of our estimate. The table votes contains the results of the survey.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
