You may need to use the appropriate technology to answer this question.
A consumer watchdog designed a factorial experiment to determine whether the miles per gallon for two manufacturer's vehicles differed and if the miles per gallon also depended on whether the vehicle had an automatic or a manual transmission. A professional driver was employed to test the vehicles. The following data give the miles per gallon for the vehicles.
Transmission | ||
---|---|---|
Manual | Automatic | |
Manufacturer 1 | 30 | 30 |
34 | 26 | |
Manufacturer 2 | 20 | 24 |
22 | 28 |
Use = 0.05 to test for any significant effect due to manufacturer, transmission, and interaction.
Find the value of the test statistic for manufacturer. (Round your answer to two decimal places.)Find the p-value for manufacturer. (Round your answer to three decimal places.)p-value =
State your conclusion about manufacturer.
Because the p-value = 0.05, manufacturer is not significant.
Because the p-value = 0.05, manufacturer is significant.
Because the p-value > = 0.05, manufacturer is not significant.
Because the p-value > = 0.05, manufacturer is significant.
Find the value of the test statistic for transmission. (Round your answer to two decimal places.)
Find the p-value for transmission. (Round your answer to three decimal places.)p-value =
State your conclusion about transmission.
Because the p-value = 0.05, transmission is significant.
Because the p-value > = 0.05, transmission is significant.
Because the p-value > = 0.05, transmission is not significant
Because the p-value = 0.05, transmission is not significant.
Find the value of the test statistic for interaction between manufacturer and transmission. (Round your answer to two decimal places.)
Find the p-value for interaction between manufacturer and transmission. (Round your answer to three decimal places.)p-value =
State your conclusion about interaction between manufacturer and transmission.
Because the p-value > = 0.05, interaction between manufacturer and transmission is not significant.
Because the p-value = 0.05, interaction between manufacturer and transmission is significant.
Because the p-value > = 0.05, interaction between manufacturer and transmission is significant.
Because the p-value = 0.05, interaction between manufacturer and transmission is not significant.
