Many consumers pay careful attention to stated nutritional contents on packaged foods when making purchases. It is therefore important that the information on packages be accurate. The null hypothesis is that the stated calorie content on a frozen dinner package is 240. A random sample of 12 frozen dinners of a certain type was selected and used to test this null hypothesis. Which of the following describes a Type I error? A. We conclude that the mean calorie content of the dinners is 240 when it actually is different from 240. B. We conclude that the mean calorie content of the dinners is not 240, when it actually is 240. C. We conclude that the mean calorie content of the dinners is 240, when it actually is 240. D. We conclude that the mean calorie content of the dinners is not 240 when it actually is different from 240.
