A random sample of prices of petrol per litre (in p per litre) from UK filling stations was taken during November 2021. Based on these data, a 95% confidence interval for the mean price of petrol per litre (in p per litre) was found to be (131.42, 142.22). Given that 1 litre is equivalent to 0.22 gallons calculate a 95% confidence interval for the mean price of petrol from UK filling stations in p per gallon. Explain your reasoning.
