You are conducting a Goodness of Fit Chi-Squared hypothesis test ( = 0.05) for the claim that all 5 categories are equally likely to be selected.
Complete the table.
Round Expected values accurate to exactly 2 decimal places.
Retain unrounded numbers for future calculations.
Round the ((O-E)^2/E) values to 3 decimals.
What is the chi-square test-statistic for this data? (Round answer to 3 decimal places, and remember to use the unrounded Pearson residuals in your calculations.)
What are the degrees of freedom for this test?
