Question

The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per yox, expressed as CO2 equalents to a 0. Os significance level to test the claw that the diferent types of which the same man amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions Click the icon to the Twwcomwww.mmasisanerencromineers 1 Data Table OCH, At least one of the means is different from the others Type A Type B Type 9 73 87 74 E-Pound to be deciso 71 75 52 5.9 54 72 93 34 77 35 73 7.5

Answer 1

Solution:-

State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.

Null hypothesis: u₁ = u₂ = u₃

Alternative hypothesis: At-least one of the u is not equal.

Formulate an analysis plan. For this analysis, the significance level is 0.05.

Source SS df MS Between- treatments 24.7137 2 12.3568 F= 36.73186 Within- treatments 8.0737 24 0.3364 Total 32.7874 26

Analyze sample data.

F statistics is given by:-

$F=\frac{MSB}{MSE}$

F = 36.73

The P-value = 0.00

Interpret results. Since the P-value (0.00) is less than the significance level (0.05), we have to reject the null hypothesis.

Conclusion:-

Reject H₀,

We can conclude that type of vehicle appear to affect the amount of greenhouse emissions.
