Problem 24

Explain what an interaction effect is. Why is it dangerous to analyze main effects if there is an interaction effect?

Accepted Solution
Step-by-Step Solution:

Step 1 of 5) Explain what an interaction effect is. Why is it dangerous to analyze main effects if there is an interaction effect (a) The data in Table 6 show the wind chill temperature for various wind speeds and temperatures. Use the data to draw a scatter diagram of wind chill temperature versus air temperature, treating wind chill temperature as the response variable and using a different plotting symbol for each wind speed. Then draw a scatter diagram of wind chill temperature versus wind speed, treating wind chill temperature as the response variable and using a different plotting symbol for each air temperature. (b) Use the model to predict the wind chill temperature if the air temperature is 3°F and the wind speed is 13 miles per hour (mph). (c) Interpret the model for a wind spee
