As part of a study designed to compare hybrid and similarly equipped conventional vehicles, a variety of classes of hybrid and all-gas model cars and sport utility vehicles (SUVs) were tested. The data showing the miles-per-gallon rating study obtained for two hybrid small cars, two hybrid midsize cars, two hybrid small SUVs, two hybrid midsize SUVs, and eight similarly equipped conventional models are contained in the Excel Online file below. Construct a spreadsheet to answer the following questions.

### ANOVA: Two-Factor With Replication Analysis #### Vehicle Efficiency Data Below is a sample dataset comprising different vehicle makes/models, classified by their class and type, along with their respective miles per gallon (MPG): | Make/Model | Class | Type | MPG | |---------------------|------------|--------------|-----| | Honda Civic | Small Car | Hybrid | 38 | | Honda Civic | Small Car | Conventional | 28 | | Toyota Prius | Small Car | Hybrid | 44 | | Toyota Corolla | Small Car | Conventional | 32 | | Chevrolet Malibu | Midsize Car| Hybrid | 26 | | Chevrolet Malibu | Midsize Car| Conventional | 24 | | Nissan Altima | Midsize Car| Hybrid | 33 | | Nissan Altima | Midsize Car| Conventional | 26 | | Ford Escape | Small SUV | Hybrid | 30 | | Ford Escape | Small SUV | Conventional | 28 | | Saturn Vue | Small SUV | Hybrid | 27 | | Saturn Vue | Small SUV | Conventional | 22 | | Lexus RX | Midsize SUV| Hybrid | 23 | | Lexus RX | Midsize SUV| Conventional | 18 | | Toyota Highlander | Midsize SUV| Hybrid | 25 | | Toyota Highlander | Midsize SUV| Conventional | 18 | #### Instructions for ANOVA Analysis 1. **Data Rearrangement:** Rearrange the data for the ANOVA: Two-Factor With Replication analysis as shown below: | | Hybrid | Conventional | |------------|---------------|-----------------| | Small Car | | | | Midsize Car| | | | Small SUV | | | | Midsize SUV| | | 2. **Analysis Steps:** - After reading these instructions, delete all text in the shaded area. - Use the XLMinor Analysis ToolPak to conduct your ANOVA: Two-Factor With Replication analysis. - After deleting all text in the shaded area, set the output range in the ToolPak to the top left cell of this area
