Question 9 A researcher conducted a goodness-of-fit test by using categorical data. Her data consists of 10 categories. Her null hypothesis states that the data occur in each category with the same frequency. If she found the test statistic x = 10.87: What is the degree of freedom of the x 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? OReject the null and accept that the data does NOT occur in each category with the same frequency. O Fail to reject that the data occur in each category with the same frequency Question Help: Video D Post to forum Submit
