The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.05 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions?

A researcher was interested in comparing the resting pulse rates of people who exercise regularly and of those who do not exercise regularly. Independent simple random samples of 16 people who do not exercise regularly and 12 people who do exercise regularly were selected and the resting pulse rates (in beats per minute) were recorded. Test the claim that the mean resting pulse rate of people who exercise regularly is larger than the mean resting pulse rate of people who do not exercise regularly. How many populations? 01 What is the parameter? O Variance O standard Deviation O Proportion O Difference between Means O Mean
