**Fill in the Blank:**A _______ is used to test the hypothesis that an observed frequency distribution fits (or conforms to) some claimed distribution.---A ![dropdown](https://user-images.githubusercontent.com/70256670/198193443-20226c08-905d-4b98-af85-3f13fd16a618.png) is used to test the hypothesis that an observed frequency distribution fits (or conforms to) some claimed distribution. ### Hypothesis Testing in Statistics**Question:**Fill in the blank:A __________ is used to test the hypothesis that an observed frequency distribution fits (or conforms to) an expected frequency distribution.**Multiple Choice Options:**1. goodness-of-fit test2. Student t-test3. F test4. one-way analysis of variance**Explanation:**The image shows a fill-in-the-blank question followed by multiple-choice options to select from. The context of the question is related to hypothesis testing in statistics, specifically concerning the comparison of observed and expected frequency distributions.**Answer Analysis:**- **Goodness-of-fit test:** This statistical test is used to determine how well an observed frequency distribution matches the expected frequency distribution.- **Student t-test:** Used to compare the means of two groups.- **F test:** Used to compare two population variances or to analyze the variances in the setting of ANOVA (Analysis of Variance).- **One-way analysis of variance:** Used to determine whether there are any statistically significant differences between the means of three or more independent groups.The correct answer to fill in the blank is "goodness-of-fit test."**Visual Aid Explanation:**The image includes a dropdown menu with the aforementioned options. The dropdown is active, and the pointer is seen hovering over it, indicating the viewer’s interaction to choose the correct answer.### SummaryTo test if an observed frequency distribution fits an expected frequency distribution, one uses a **goodness-of-fit test**. This type of test evaluates the null hypothesis that the frequency distribution of certain events observed in a sample is consistent with a particular theoretical distribution.
