Tuesday	18
Wednesday	24
Thursday	28
Friday	30

He expected to see 25 visitors each day. To answer whether the number of visitors follows a uniform distribution, a chi-square test for goodness of fit should be performed. (alpha = 0.10)

What is the chi-squared test statistic? Answers are rounded to the nearest hundredth.
