Chi-squared Goodness of Fit I

The reason why you expected that the students would like the part advert is because of a statistic you had heard. You were told that most college students go to parties regularly (60%), some go to parties occasionally (30%) and a few never go to parties (10%).

To test whether this is indeed true, you decide sample 100 college students, as about their party-going habits and run a Chi-squared goodness-of-fit test on their answers.

Two data tables are saved in your console - x and z. One contains your expected frequencies and one is your observed frequencies. Have a look at both by entering z and x into your console.

Which data table is which?
