Well, the expectation of Average Number of Complaints being different is, Indeed, based on the descriptive statistics, the averages along with, standard deviations suggest variability in complaints across regions, indicating the possibility of different average complaints. Question b- The hypothesis for evaluating average number of complaints is: The Null Hypothesis (H0) is the average number of complaints and is the same across all four regions. Regarding the Alternative Hypothesis (H1), the average number of complaints is different across at least one region. Question -c-I Run ANOVA in JASP ANOVA Output Table The import pandas as pd # Create the dataset for analysis data = "Region": [1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4], "Complaints": [0, 1, 3, 1, 0, 1, 3, 1, 2, 0, 4, 3, 5, 2, 4, 5, 4, 3, 5, 4] df = pd.DataFrame(data) # Save the dataset as a CSV file for JASP import 2 1 3 3 1 1 4 1 0 The questions are below. I. The F-statistics alongside, p-value: F-statistic: 14.55 p-value: 0.0002. Conclusion: Ultimately, since the p-value “0.0002” is less than the significance level “0.05”, Indeed, I reject the null
