Ms Access Data


1. The problem asks to extract and answer question 1 from the file named 222.jpg in MS Access format. 2. Since the user provided data: 30, 20, 40, 20, 30, 60, 80, 20, 40, 20, but no explicit question text or context, we interpret question 1 as a request to organize or analyze this data in MS Access. 3. MS Access is a database management system used to store, retrieve, and manage data. 4. To answer question 1 in MS Access format, we would create a table with a single column (e.g., "Values") and insert the given data as records. 5. The steps to do this in MS Access are: 1. Open MS Access and create a new database. 2. Create a new table named "DataValues". 3. Add a field named "Value" of type Number. 4. Enter the data values 30, 20, 40, 20, 30, 60, 80, 20, 40, 20 as rows in the "Value" field. 6. If the question requires analysis, such as finding the mean or frequency, we can use queries: - Mean (average) is calculated by $$\text{Mean} = \frac{\sum \text{Values}}{\text{Number of values}} = \frac{30+20+40+20+30+60+80+20+40+20}{10} = \frac{360}{10} = 36$$ - Frequency of each value can be found using a "Totals" query grouping by "Value" and counting occurrences. 7. This approach organizes the data in MS Access and allows further queries or reports as needed. Final answer: Create a table "DataValues" with a numeric field "Value" and input the data. Use queries to analyze as required.
