- The Las Vegas Review-Journal (R-J) posts an article on their website reporting on a poll they conducted for the upcoming Senate election. Their poll asked likely Nevada voters who they intend to vote for. The results were: Catherine Cortez Masto with 45%, Adam Laxalt with 41%, 14% undecided, and they report that their poll has a +/- 3.5 percentage point margin of error. The article's headline is "Cortez-Masto Leads Laxalt by 4 Points." Is the R-J right? That is, can we be reasonably sure (95% confident) that Cortez-Masto really is ahead of Laxalt? if we had the raw data we could just load it into R and do a quick difference of means test, but we don't need the actual data to figure it out in this case. In your answer, address the following: (1) Is the R-J probably right that Cortez-Masto leads Laxalt? (2) how you came to that conclusion?arrow_forwardAfter the premiere of the new comedy Bumblebee, moviegoers were asked in a quick poll whether they liked the movie.

- Find another classmate’s initial post and write down the margin of error that they calculated. You will use that value in another context. As another election cycle begins this fall, you will likely hear newscasters state poll data and then mention the margin of error. For example: "Polls show that among likely voters in the Make-Believetown Governor’s race, Bad Wolf is currently leading with 43% of expected votes, Little Pig has 41%, and 16% are undecided. The poll has a margin of error of 4%.” Instead of the 4% margin of error currently in the example, use the margin of error from your classmate as the new margin of error% for the poll. Write a brief paragraph explaining who you believe will be the next imaginary governor of Make Believetown and why. Use the information you know about the margin of error to make your case. My new margin of error for classmates is 10.08408.arrow_forwardThe San Diego union tribune choose a question each week and asks readers to call in their responses.
