A researcher conducted a goodness-of-fit test by using categorical data. Her data consists of 7 categories. Her null hypothesis states that the data occur in each category with the same frequency. If she found the test statistic $\displaystyle \chi^{{2}}=$19.94:

What is the degree of freedom of the $\displaystyle \chi^{{2}}$ statistic?

What is the P-value of the goodness-of-fit test? (Round to 3 decimals)

Given the significance level of 0.1, what can she conclude from the test?
