Step 1: Uploading the dataset The data for this discussion is included in a CSV file called etf_returns.csv. It contains ten-year returns of 30 ETFs for three sectors: financial, energy, and technology. The read_csv method in pandas can be used to upload the CSV. Click the block of code below and hit the Run button above.

The method f_oneway is used to perform this test. The inputs are individual dataframes of all groups (in this discussion, groups are sectors).

Once you have made your calculations, complete this discussion. The script will output answers to the questions given below. You must attach your Python script output as an HTML file and respond to the questions below. In this discussion, you will apply the statistical concepts and techniques covered in this week's reading about one-way analysis of variance (ANOVA). An investment analyst is evaluating the 10-year mean return on investment for industry-specific exchange-traded funds (ETFs) for three sectors: financial, energy, and technology. The analyst obtains a random sample of 30 ETFs for each sector and calculates the 10-year return of each ETF. The analyst has provided you with this data set. Run Step 1 in the Python script to upload the data file. Using the sample data, perform one-way analysis of variance (ANOVA). Evaluate whether the average return of at least one of the industry-specific ETFs is significantly different. Use a 5% level of significance. In your initial post, address the following items: 1. Define the null and alternative hypothesis in mathematical terms and in words. 2. Report the level of significance. 3. Include the test statistic and the P-value. See Step 2 in the Python script. 4. Provide your conclusion and interpretation of the test. Should the null hypothesis be rejected? Why or why not? 5. Does a side-by-side boxplot of the 10-year returns of ETFs from the three sectors confirm your conclusion of the hypothesis test? Why or why not? See Step 3 in the Python script
