Using the data below, is there a strong evidence to indicate that the standard deviation of the diameter of oranges exceed 0.5 cm? Use a level of significance of α = 0.05. population parameter What is the Critical Value What are the sample STANDARD DEVIATION What is the Standard test statistic?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 0.025 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions.
