(Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample? For this calculation, use the degrees of freedom reported from the technology you are using. (Report answer accurate to…Use the sample of the greenhouse gas emissions of 32 different cars. (The amounts are in tons per year, expressed as CO2 equivalents.) Use a 0.05 significance level to test the claim that all cars have a mean greenhouse gas emission of 8.00 tons. Find the statistic, p-value and the critical value (or values).
