A Test Is Conducted At The 05 Level Of Significance To Determine If The Mean Tem

A test is conducted at the .05 level of significance to determine if the mean temperature in an oven is less than 400 degrees using a random sample of 40 ovens of the same model. Assume the population standard deviation is known to be 10. Find the probability of committing a type 2 error if, in reality, the mean temperature is 396 degrees.
