Please help to do these questions, Thank you so much!
Three different brands of tires were compared for wear characteristics. From each brand of tire, ten tires were randomly selected and subjected to standard wear-testing procedures. The average mileage and the sample standard deviation (both in 1000 miles) obtained for each brand of tire are shown below. The overall mean is 36. 2) Brand C | Brand A | Brand B Average Mileage37 Sample Variance 38 What are the numerical...

Crescent Oil has developed three new blends of gasoline – Blend X, Blend Y and Blend Z, and must decide which blend or blends to produce and distribute. A study of the miles per gallon ratings of the three blends is being conducted to determine if the mean ratings are the same for the three blends. Five automobiles- 1, 2 3, 4 and 5, have been tested using each of the three gasoline blends and the miles per gallon ratings...

PLease answer the questions given, I dont need just the conclusion of anova test Three brands of gasoline (Shell, BP, and Marathon) were deliberately selected for an observational study. The study was conducted to understand which brand of gasoline among the three selected is cheaper across the metropolitan areas of mid-west. A gas station for each brand of gas from 10 metropolitan areas were randomly selected for the study. It is a well-known fact that, the price drivers pay for...

One-Way ANOVA and Randomized Black Experiment (Two-Way
ANOVA)
An automotive engineer wanted to determine whether the octane of gasoline used in a car increases gas mileage. He selected six different brands of car and assigned a driver to each car. Then 5 gallons of the gasoline selected was placed in the car. The car was driven around a closed track at 40 miles per hour until it ran out of gas. The number of miles driven was recorded and then...
