Car batteries are manufactured with two different production methods. The population mean and standard errors (in years) for the life of batteries produced with each method are as follows: • Production Method One: µ1 = 4.0, σ1 = 0.37 • Production Method Two: µ2 = 4.07, σ2 = 0.31 Assume that a researcher, who knows the population standard deviations, decides to test whether these two production methods result in the same mean batttery life using a sample of n1 = 35 and n2 = 32 at the 5% level of significane. Calculate the type I and type II errors from this test
